Since its premiere in 2007, the series became TV’s biggest comedy and its characters and sayings have become a part of pop culture. Loyal fans have now tuned in for 12 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 was a challenge to keep the content fresh and exciting, leading to some great seasons and others that were more mediocre.
