Parks and Rec is my favorite live sitcom going right now. Really good stuff.
My problem with the first season wasn't so much its aping of The Office as how unlikeable the characters were. That's not an issue with the zanier, more cartoonish comedies (AD, Community, Archer, etc), where you can play the selfishness and callousness for laughs, but the more realistic you make the setting, the more off-putting it gets. Unless you get to the point of "so brutally awkward it's funny" but I don't think P&R was ever going to get close to that.
Anyway, even if it gets subsumed by relationship stuff and general sitcom aging disease in the future it's great now and everyone should check it out.
