I'll be honest I gave Big Bang Theory several chances and it feels phony and manufactured. The nerd stuff feels like a gimmick to try to tap into the geek culture which has made what were once nerdy obsessions like video games, science fiction, and comic books into something that is mainstream and profitable. Some Executive at CBS realized that us "nerds" have disposable incomes, weren't the basement dwelling creepy minority we were usually depicted as, and also watch TV.
This is exactly my problem with the show. It feels like it was devised and written by a bunch of studio suits who were like "so, this is what nerds are like, right? Pretty much just Star Wars and Xbox. We'll throw in a Schrodinger's Cat joke to make it seem smart" and the general (ignorant) public is like "yeah! Totally! Those silly nerds!" The popularity of the show is baffling to me, although at the same time it isn't at all. And for some reason Jim Parsons is like nails on a chalkboard to me. Not to shit all over a show in its own fan thread, but... Yeah I'm not a fan.
