I don't get the hate for Big Bang Theory. I don't think they are laughing at or poking fun at geeks. I think it's pretty good natured. I think the science in it is meant to be above-average (is it?) but it ain't meant to be proper nuclear physics and stuff. Granted, it is not even in the same league as IT Crowd (which is easily one of my favourite shows) but it's not that terrible, is it?

What the IT crowd has in its corner is some absolutely absurd moments that make up for the hokey bits (laugh track, etc.):
