I was a hardcore Community fan. I'm talking, there from the very start, one of those fans who campaigned to NBC when the show was moved to midseason in Season 3 by sending them moustaches in the mail, writing to them, all of that jazz. I used to hit up Pirate Bay every single Friday morning at University to grab the newest episode (I lived in Australia), preordered the DVDs as soon as I could and campaigned like crazy for a movie even years after the show ended.
Now that I'm out of that bubble.... the show is just meh to great. Seasons 1 and 2 are almost perfect. Season 3 had highs but honestly it marked the moment the show set on a path that turned the characters into cartoonish versions of themselves and really set the show up for what I believe was getting too silly and trying to pass it off as meta. "Flanderisation" is an overused term in criticism these days but Community is especially guilty and they did it so quickly compared to some other shows that do it
Season 4 is well publicised, but I actually think Season 5 was as bad overall. Tonally all over the place and the finale was straight up bad.
Season 6? I liked it more than most. The new characters were okay and they were never gonna hold up to the others but they did well. Shirley wasn't really missed but Pierce and especially Troy were integral to that show.
I'll always cherish the first 3 seasons as some of the best television I've watched and been a part of. While it's probably slipped from my Number 1 to low in my Top 10 in only a matter of a few years, it's still totally worth watching
