The Big Bang Theory, Season 12 poster

Leonard and Sheldon are brilliant physicists – geniuses in the laboratory but socially challenged everywhere else. Enter beautiful, street-smart neighbor Penny, who aims to teach them a thing or two about life. Despite their on-again, off-again relationship in the past, Leonard and Penny have finally gotten married. Even Sheldon has found a female companion, entering into a “relationship agreement” with neurobiologist Amy Farrah Fowler, and he recently took their relationship to the next level by marrying her after a long courtship. In their free time, Leonard and Sheldon enjoy fantasy role-playing games with their ever-expanding universe of friends, including fellow scientists Raj, Howard and Howard’s adorable microbiologist wife, Bernadette, who is adjusting to life with their two children.

No 16 episode  Girltrouble85  1 star

Why is it that my iTunes tv not showing episode 16? I had to come to the store to download it.

How to get all seasons

I was watching on Amazon, until now  LordVoldemort09  5 star

I am so happy to get this season. It is fantastic! And well worth spending more money to avoid that God Damned CBS All Access. You can't even purchase episodes with it. Its basically renting, only difference is your paying 8 bucks a week to rent and watch what you can't own. and if you cancel, but decide later on to watch again, you have to purchase again, it's stupid. Sorry, I got of topic, point is the season is great, and thank you Apple!

Love Big Bang theory  Ewok63  5 star

It’s by far one of the best sitcoms ever done. It reminds me of my friends who were in Radio Astronomy club together and we had personalities like all of the characters. I wish this show could always continue I will miss it so much. It’s so real for me in allot of episodes my geeky great friends reminds me of some of their shows. I’m hoping maybe some day they could do a movie or something. Thank you all for doing this amazing clever show.

Bad stuff come on it died they kill James

One of the best modern comedy shows  CMac117  5 star

I have loved this show from the very first episode in season 1. Great writing, wonderful characters and a truly perfect cast. The evolution of each character and their relationships to each other through the history of the show has been perfect. It's one of those shows that you can watch over and over again and NEVER be disappointed!

Show is on it's last legs  vrdavids  2 star

Show was halrious the first 3 seasons. Was just OK in the mid seasons. Now however the shows feels old and tired and the laughs are few and far in between. They ruined the show once everyone was in a relationship and it feels like I'm watching Friends instead of the Big Bang Theory.

Great show, but...  JP1075  5 star

I just wish the season pass was a lot less than $40.

Irritated  BritishWineGuy  1 star

Not able to get episode 3 even though bought season pass.


I just spoke to apple and asked why the 3rd episode isnt' availale yet as its aired a week ago. answer is they have to wait for the provider to release it for download. I said then apple shouldn't sell something they actually don't have. I still think a crock of.... I've purchased many tv shows and not once has this happened its release asap. obviously some type of excuse but I won't prepurchase again the 1 star raiting is based on apple and not the actual tv show

Not happy  💥💥💥Alana 💥💥💥  1 star

I go to watch the shows that I purchased and all I get are the previews.

It’s the last season guys...  RS-987  1 star

To the writers: PLEASE do not go back to the days of unwatchable Raj or trying to teach the viewers what not to do in relationships. Just be funny. Go back to the Infamous thanksgiving episode if you ever question what viewers want. We want to laugh until it hurts. We don’t want simplistic life lessons. More Howard impersonations of celebrities, more personality quirks that are funny and are to be celebrated. Please stop writing Raj to be someone who either annoys us or makes us feel like we should feel sorry for him. Enough is enough. Just be funny. Get it? I’m giving you four stars in hopes you will give us what we want. There are a couple of seasons we can’t unsee, despite desperately wanting to, so please don’t make it a third.

Why watch if certain cast members don’t want to be there?

iTunes is useless  Bevfactor000  1 star

So glad I learnt from last season and didn't buy this season in advance. Waiting 5 months between episodes is an absolute joke. Don't waste your money. Had to give 1/5 stars as 0/5 stars (for iTunes not the TV show itself) wasn't an accepted by the website.

Still waiting  Manx06  1 star
