All I know is that the Chaos Theory episode was a just as good as any episode from season 1 (except for Modern Warfare of course) IMO.

I don't care that Community isn't accessible, most great shows aren't accessible if you just watch one random episode because you lack familiarity with the characters and situations. Granted it is expected that sitcoms shouldn't be like this, but even shows where you can just jump in and enjoy an episode with no background are way better once you catch up with the backlog. Though, I can't fathom who would watch one episode of Community and be able to not want to see every episode.

Wait, I guess I can. There are people out there who like Two and a Half Men.
