It is tough to review this show because its quality changed so much over its lifetime. Reviewing Big Bang today, when it is in its 11th season means having to go back to seasons 1-3 to give credit to the show's creators. Back then, they pioneered their quirky and entertaining portrayal of the show's unusual protagonists. However, seasons 9 and later has been disappointing. The writing grew stale and the jokes aren't funny or edgy anymore. Big Bang has overstayed its welcome and has become a hollow shell of its original self. Now it is just the vehicle for the actors and creators to continue to collect their paychecks.
