This was a great show for seasons one and two and is highly recommended. Don't bother with season three - its awful. It's not funny anymore, the writing is terrible for season three.

In seasons one and two, you feel like they're actually at a college. For season three, that feeling is lost. Season three stories have minimal plot. Any story in season three focusing on Abed is especially bad. His character is not very interesting, and painful to watch for extended periods.

The cast has been excellent throughout, too bad they have no material to work with for season three.
