I enjoyed the last season but not the finale. After first three episodes I've hinted that they're gonna have some big drama/conclusion at the end of the season, but it was underwhelming in IMO.
Also, I like their new approach where they they plan the whole season as one complete story with few sideline stories, instead of before - where every episode was for itself.
What I don't like is that they base a lot of episodes on a topics that are currently happening only in USA. First, rest of the world wouldn't/can't probably get the joke. Second, it does not age well. For example: when you watch earlier seasons, topics were universal and are still going today. Now, in a few years, if somebody watches last season episode about Redskins, Zimmerman or similar they would've have probably no idea what are they talking about.
Still, looking forward to new season if they continue this "one season-one big story" deal
