First two seasons were great. After that I felt like things went slowly downhill and by the middle of the third season I decided to stop watching it. I haven't watched anything since, so perhaps it's picked back up but there's so much great TV nowadays that I don't feel compelled to come back to it (aside: why is it that movies of late have been so trout and television seems to be, as a whole, getting better and better?).

But yeah, first two seasons were some of the best comedy television I've ever seen.
