Season 1 seems rather grounded but for seasons 2-4 they just run wild and it's very fun to watch. The characters are funny and most of them play well off each other. Seasons 5 and 6 were a bit of a letdown and suffered at the loss of cast members but is still ok. The best parts of the earlier seasons more than make up for some of the slower episodes of the latter ones. Definitely worth watching, even if it's just to see Troy and Abed.
