The episode that had the greatest impact on me on my first watch was 'Debate 109', because my taste in Community episodes is painfully obviously influenced by my 'shipping preferences. I rewatched it last night with my housemate. Having company meant I couldn't rewind and rewatch scenes, of course, so this morning I woke up at seven, went straight to the television and watched all the Jeff/Annie bits again multiple times. I'm deeply ashamed of myself.

Hmm, what episodes do I like for respectable reasons? I remember really enjoying the vaguely post-apocalyptic tone of 'Modern Warfare', the paintball episode, so I'm looking forward to reaching that.

I'm sorry to hear that the fourth season isn't great, but it's certainly good news that the show managed to recover!
