It doesn't develop its characters like most modern comedies. Rather, it establishes them as archetypes and then puts them in different situations each week. In some of the later seasons, there is a bit more character development. The show is ambitious in approach, but the result is that it can be hit-or-miss. Other comedies that commit to character development can afford poor episodes along the way because if the audience has grown to love the characters, the show is given a lot of leeway. Consequently, this is why I have a hard time with House of Cards. The plot and pacing were terrific in the first 2 seasons, but I can't stand every character on that show. The third season is not as well written and because I can't stand the characters, I'm having a hard time finishing it.
I digressed, but I agree with you that Community is funny. It's also very ambitious, which I appreciate.
