I went into this prepared to adore it; I didn't mind the changing supporting cast, and I love Greg Grunberg so I'll give anything he's in a try! But this just fell flat for me. I think a few of the stories are okay, but not compelling enough to hold me, and a couple of the main characters have changed so completely from one show to the next that it's hard to really get a grip or start feeling invested in them.
The other thing that bothered me was that the writers seem to be trying to shock us into thinking it's hip or cool by putting the characters in semi-impossible or unrealistic situations. It's like, sure, those things COULD happen but it's far more likely they wouldn't. Are the main characters going to wake up at the end of the show (which I expect will be soon) and find out they were all dreaming? That would make more sense than a lot of the scenarios, imo.
