I love the accusation that people who think Big Bang Theory sucks "don't get the jokes". Most of the people who love it have no idea what the scientific principles in the punch lines are, but they laugh anyways, because the laugh track tells them to.
I don't particularly enjoy shows that are a revolving set of punch lines, which is what Big Bang Theory is.
Currently airing comedy shows that I like:
-Parks & Rec
-It's Always Sunny
-The League
-South Park
Big Bang Theory is basically the same structure as 2.5 Men, but with nerds instead of Charlie Sheen. My disdain for the show really has nothing to do with the nerd aspect (Freaks & Geeks is great), and everything to do with unfunny/unclever writing that's basically a rehash of a million other shows, but dressed up to take advantage of the rising popularity of nerd culture. It's soul-less money grabbing at it's finest. And people eat that **** up.
