None quite so quickly and with quite such consistency. I liked the show best when it was grounded, sort of slacker fantasy. It's gotten less grounded. I'm obviously impressed by some of the experiments on a creative level but I think it makes the show, I dunno, less appealing. In general I feel like most of the character development past Mixology Certification has been not very enjoyable. I really liked the score and music they used in the early part of season 1, which I thought had a sort of bouncy ebullience... but that's receded. I never liked Pierce, I haven't liked Chang since he got promoted from recurring to starring, the Dean works best in smaller doses and yet his role has expanded. I think Troy has sucked since the bizarre he's-not-fit-for-real-university-but-he's-a-trade-savant twist. I agree that Britta didn't work as a sort of compelling central romantic lead but I think everything they've done with her since then has kinda been a mess. Shirley I could take or leave. Abed is alright but I felt most of season 3 and season 4 was indulgent and pretty detached from reality as far as he was concerned.
Given the rather steady shedding in the ratings and the fact that the show got less critical buzz in S3 and S4, I suspect I'm not the only one who feels this way.
I'm interested to see what Harmon brings to the table this season. I hope the hiatus gave him a renewed creative energy. At this point the show is pretty low investment for me, I'll watch it but it's not something I'm really, I dunno, fixated on or looking forward to.
I feel like a jerk for kinda being a cynic in a room full of people so excited to see what they hope is a new dawn for the show. I'll end on a positive note. There are some things I like in recent seasons.
The Dean and Jeff doing karaoke is one of the best individual scenes of the series to me. It's something that gives me gut-busting, side-splitting laughter. The background images are so asinine, Jeff's off-key singing versus the Dean's enthusiasm, the terrible transitions, the awful camera zooms that echo the worst of community access TV, the montage cuts to Pierce's bizarre rat pack fantasy flashback, and especially the ending shot with Jeff doing the outreached arm and the wistful look into the distance. It's masterful.
