The Big Bang Theory Season Twelfth and Final Season + Season 11 (Bonus)
The aspect about The Big Bang Theory that always interesting was the original premise. Watching a group of socially awkward intellectuals and pop culture nerds try to fit in with their normal neighbor and her friends had a unique twist to it. This premise allowed for an unlimited amount of guest stars that would top any comic convention wishlist paired with the best part of this show: the science.
As the series introduced more female characters they diverted away from the unique science aspect of the show and focused more on the relationships between the characters. While this is a very important piece of sustaining a series for so long, it should not have come at the almost complete cost of the show's original premise. The female characters have in turn become less three-dimensional than initially shown and become nothing without their nerdy counterparts.
The funny thing is that this show is shot in front of a studio audience and yet the laughter feels more forced than a dubbed over laugh track. The jokes tend to veer towards Sheldon's selfishness, Leonard's pessimism, Howard's racism and Raj's sexism which has essentially made these characters caricatures of their former selves. It has become tiresome to watch the same situations play themselves out with most of these characters never learning from these experiences.
While some shows reinvent themselves to keep things fresh after ten seasons, this group of friends and their stories have seemed to run their course. From its humor-less, tiresome situations to its shift from its scientific premise, this show has fallen from grace as one of the best original sitcoms so it's unfortunately not worth the watch.
