I just don't have the time to offer up weekly thoughts on all the shows I watch, but here are some thoughts on the NBC sitcoms
Parks & Recreation: The show continues to be the best overall sitcom on television. Not much else needs to be said.
Community: After an average start to the season (for this great show), Community finally stepped up and delivered the great "alternate time lines" episode. While that episode seems like a "gimmick" episode on the surface, to me it was much more character driven than most of the "normal" episodes. Unlike the paintball episodes (which are great in a different way), this episode truly explored the natural tensions between the characters because of their unique traits and flaws. When Community finishes up its run (my guess is it gets one more season after this one), this will go down as my favorite episode. This episode was better than any individual episode of the current Parks & Rec season, but the season has been too inconsistent to be considered better right now.
The Office: The show's adjustment to losing Steve Carell has been a struggle. The show is so desperate to make Ed Helm's character seem likable that they have seemed to have forgotten to make him funny. The funniest thing the show has done so far this season was the running gag with Mose in the Garden Party episode. Shouldn't it be troubling that funniest thing revolved around a character that only pops up once or twice a season. The show has lost its way, and I don't see any hope that the show will become consistently great (or even just funny) again.
Up All Night: Stop watching after the second episode; from what I have read, the show's problems are pretty well-defined at this point, and I don't have any nostalgia for it (like the Office) to go out of my way to see it.
