- Great show! My favorite one5 star

Loved the show since season 1

- Play next feature doesn’t work1 star

Have several seasons bought through iTunes and they work well. This one doesn’t support the play next feature. Each time you try clicking on it it wants you to purchase the episode. Only way to play it is through the library and shows. Gets annoying as it doesn’t save the last episode watched.

- Price1 star

I was planning on buying this but, I think it went up $100 wasn’t it at 99.99?

- Apple WILL steal your money1 star

This does not work through Apple TV watch now. After going back and forth with apple for six months, they stated that because it works through your library, there will be no refund. For a series with 20+ episodes per season, once you get past season five, you'll need to scroll past hundreds of episodes just to get to the last one you were on. Itunes customer support is an absolute joke. I went through 5 different representatives because after 3-4 weeks, each one would ghost me and stop responding. This is their final response after six months. The final and very thorough investigation of your previous history with this case and refund request has now been completed and finalized. It was found and agreed upon by all appropriate Apple departments that while this particular series doesn’t play like the other series, you can still watch them and they do still play as formatted and as they were made to do. All series, subscriptions and apps do not work the same way. Therefore, Apple will not be refunding that series. There is no other escalation path. That is Apple’s final answer. This " thorough" investigation was one day, no input from me and no insight into anything. They know the series is broken and are actively roadblocking refunds.

- Doesn’t support up next!!1 star

It’s ridiculous and really annoying to have to scroll for 5 minutes to get to an episode and not have the next episode auto play. I bought the Cheers series and it’s a completely different experience. I have no idea why they can’t fix this. Buyer beware

- Terrible Implementation1 star

In order to work to choose the episode, you need to go into library and pick out the specific library which is a hassle... especially on Apple TV. I have many other Complete Series and they work completely fine from the Search and with up next. Avoid this one. Terrible Implementation

- Please fix2 star

Please configure this show to automatically play the next episodes. The show will not always have the next episode lined up to play. Instead you have to scroll to the next episode.


The complete series does not support up next on all devices. When selecting the episode from up next, I’m asked to pay for it. There’s not fix and Apple doesn’t care.

- Bazinga!!!!5 star

My Favorite Comedy show in years all of the characters including Sheldon Cooper, Howard Wolowitz, Raj and Leonard Hofstauder were all likable and funny this show is my favorite thank you I-tunes🧠❤️

- Useless1 star

Love the show, but the way Apple sold this is complete garbage. I’ll be requesting a refund and going with Vudu instead. Cant believe how much Apple has fallen the past few years. Profits over quality seems to be the direction they’ve headed

- Continuous play bug1 star

Like every other 1 star review, you can’t play continuously.. if you open up the TV app on and browse to watch now, the “up next” is the next episode and when you do click it, it asks you to buy it.. I’m guessing you have to scroll though to find your last episode.. like most have said, it’ll be bumped to 5 star once fixed

- Fix bug please!!!1 star

Show is great but cant watch on continuous play please apple fix this then it would jump to 5 stars

- Great show... poor execution3 star

This show is very funny and the cast has great chemistry. The comedy is a bit over used but never enough to make you want to turn the show off. Now to address the problem everyone is having. Yes this box set is broken and you cannot simply jump to the next episode. However the series is on sale now for $19 a season. At 12 seasons that’s $240 and this box set is $100. At more than a 50% savings if you can’t take a few seconds to scroll through a list and find the episode you left off on that’s just lazy. I’m not excusing Apple for the way this is set up and I hope it does eventually get fixed. If it ever does my review will jump to 5 stars. However, if it bothers you then you can always pay the full price for individual seasons

- Great show horrible collection1 star

Apple DOES NOT split up this collection by season. It’s one continuous season and there was no continuous play.

- Don’t Buy This Crap Bundle!!! BROKEN1 star

Just like almost all the other 1* Reviews, this is broken and only as one long season that won’t remember where you left off. Every time you log back into it, you have to waste your time scrolling through all the episodes until you find your bookmark. THIS IS BROKEN and Apple doesn’t care to fix it. It has been this way for about a year or so. Looks like Apple greed is larger than their desire to satisfy customers :-(. Fix this Apple or just lose more business....SMH.

- Over a year and still doesn't play the correct way1 star

Vudu has it for $79.99 and will play correctly. No need to go through your collection to get the next episode. I requested a refund. Who would think a Walmart based company would have a better streaming service then Apple. Is this just the start of the fall of Apple?

- That’s my spot 🛋5 star

One of the greatest shows of my life it’s helped me get through tough times in life and I’m so thankful for this show live long and prosper 🖖

- Cannot watch next episode1 star

1. Have to browse for few minutes if want to watch the latest season 2. Go to Watch next episode and being asked for buying it What is wrong with you Apple. I bought the entire collection and I cannot watch a single episode, really?!

- Bundled as one big season!1 star

The series is sold as one big season. It shows up in up next but attempts to watch the next episode are directed to the individual seasons which have not been purchased. Furthermore, navigating to the purchased, bundled season in the tv app reverts back to S1E1 so you have to scroll through all previously viewed episodes to find the next episode. Can’t wait until I’m on season 12 and have to scroll through a couple hundred episodes each time I want to watch. This is horrible Apple! Please fix this!!

- Apple screws it up again!1 star

Paid $119.99 and Apple is saying I have to repurchase them on every episode I watch!! Come on Apple! GET IT TOGETHER!!

- One of the best sitcoms ever5 star

This and The office are my favorite shows ever.

- Not Synced with Apple TV up next2 star

Apple, you are slowly fixing the issues. The episode shows up in next up, it even knows which one I’m watching..... But.... like everyone else is saying, Apple wants you to repurchase the episode. 🤦🏻‍♂️ Almost there apple... so you have to go into your own tv purchases to watch it. Outside of that, the quality is good and it at least keeps track of which episodes I have watched.

- !!!2 star

Can this be cheaper? I love BBT but gosh it is expensive, do a discount on Black Friday

- Shows up in “Up Next” in Apple TV app, but says I need to purchase1 star

Changing my review AGAIN back to one star. They fixed the show showing up in “Up Next” but when you click the thumbnail to play the episode, it takes you to the store with a price tag for the episode. Horrible. Please fix for the Apple TV app.

- Does NOT sync with Apple TV Up Next1 star

Chiming in with other reviews here and stating beware that this series will NOT show up in your Up Next queue through the Apple TV application. I have not had this happen with other digital box sets that I have purchased, and maybe Apple/iTunes can find a way to fix this. Due to this, I'm not totally happy with this purchase and dropping a 1-star review at this time.

- Love this show!5 star

I miss this show and had to buy the complete season. Not happy with the way it's laid out but hey at least i have all the episodes and some extras as well. The lay out is a little tricky but at least everything is there and for a great price.

- ❤️5 star

I love this set!! The extra videos are awesome!!

- Horrible, beware1 star

This is sold like a separate season, a single season.... therefore when you buy you own just a box set not seasons 1-12 but a single season of all episodes. This is told to me by Apple that is what they did.... therefore if you buy this and then go to search in their new Apple TV app for the Big Bang theory any season and any episode (expecting to be able to watch ANY as you bought all the seasons right?!?, wrong!!!! It shows like you don’t own any of it, why because you don’t own each individual season but a separate season made by them as an alternate season one which has all episodes assigned but does not connect or correlate with the rest of the iTunes system. Horrible!! I feel cheated!!! Lied to and unable to fully enjoy my purchase!!! Any other streaming eg. VUDU does not due this as bundles include each individual items within the bundle, iTunes does not!!! Would have went through VUDU instead had I known as this was my first iTunes tv box set purchase... never again Apple.

- Great Deal!5 star

Appreciate getting the complete set plus some extras for 50% off!

- Wrong sale price3 star

iTunes Store advertised a 50% off sale on the Complete Series of The Big Bang Theory. It was originally $119.99, but instead the price was $99.99.

- 🔥5 star

Such an amazing tv show with a very good deal!

- Greatest comedy EVER5 star

I love this show, it’s my all time favorite comedy

left888 - NOT AT $2001 star

Wow, the greed of iTunes/Apple $200 ... ain't gonna happen in my lifetime. Get it down to $60 and I would think about. Remember iTunes. We've all seen these episodes many, many times already. Price accordingly.

AndyAA1030 - Watch next function error1 star

Purchased the full season excited to see that it did in fact include bloopers and extras that come with the DVDs. As I prepared to watch the series endlessly I discovered that the next episode did not play and instead asks you to purchase the next episode. To watch the next episode you have to scroll through 100s of episodes and play each time. I did see that previous comments had stated this but were left awhile ago and figured it should have been fixed by now so I am updating that this is still an issue. If this is ok for you this is the perfect complete series for you.

Kris Atkinson - flawed release1 star

using Apple TV 4K, “Watch Now” ALWAYS links to the next episode on the SEPARATE individual season, NOT the complete series. So, after purchasing, clicking to watch the next episode in Watch Now directs to the STORE PURCHASE PAGE!! I have to click through to my Library, find the show, then find the episode I was on to resume playback. NO OTHER show has this linking problem. reported to Apple and getting told this is “expected functionality”, and there is no way to escalate the issue to the content publisher. Attempting to report issue to CBS is fruitless - no response on social media. only “workaround” is to get a refund for this purchase, and buy all seasons separately at 3x the price.

Skippy St-H - Priced too high1 star

As stated the price is higher for a digital download, it seems like a waste.

sazzafrazz82 - Not sure why the difference????1 star

Box set selling in store for $129.99 and digital download is selling for $199.99.... can someone explain this to me?

Noah Blackmore - Great Show5 star

Really good show.

Enomos - Disappointed1 star

I am quite disappointed that I can’t play these episodes through the tv app as they are listed as seperate episodes
