Back in 2007, no one could have predicated just how big of an impact The Big Bang Theory was going to have when it first aired. Since 2007, the series has become TV’s biggest comedy and its characters and sayings have become a part of pop culture. Loyal fans have now tuned in for 10 seasons and in those seasons have seen a lot of highs and lows when it comes to the lives of Sheldon Cooper, Leonard Hofstadter, Penny, Howard Wolowitz, Rajesh Koothrappali, Amy Farrah Fowler and Bernadette Rostenkowski-Wolowitz. Like many long-running series it has been a challenge to keep the content fresh and exciting, leading to some great seasons and others that were more mediocre. Here (http://www.fame10.com/entertainment/__trashed-3/2/) are all 10 seasons (http://www.fame10.com/entertainment/__trashed-3/3/) of The Big Bang Theory (http://www.fame10.com/entertainment/__trashed-3/4/) ranked (http://www.fame10.com/entertainment/__trashed-3/5/):

Alan,

I think Season 7 was good. I believe the first 7 seasons were excellent and Season 8 should have been the one where they tie up all the loose endings and go to Syndication Heaven.

1
8 (7 and 8 were a nice rebound and a settling in of the revamped format)
7
4 (the first year I could tell things were going downhill)
9
10 (9 and 10 are good, but if only seasons 1-4 existed, that's okay. Amy changes personality so many times in 5 and 6 as to who she wants to have sex with that the writers didn't know what to do with her.)
5 (the episode with the chair was hilarious)
6

(haven't seen enough of 11 yet)
