The last episode was my favourite by far; my problem with this season was that I didn't like and couldn't care less about any of the characters, but somehow I now like Nick. The ginger seems alright but we've seen next to nothing of him, Frankie's just bland, Minnie is a manipulative bitch (I'm guessing the only reason she tried to get the group together was so that Nick would seem like more of a bad guy when his infidelity was revealed and more friendships were torn apart, or just because she realised she'd have no one otherwise), Liv is a frustratingly short-sighted coward who thinks she knows it all, the metal guy is entirely self-absorbed (beyond being nothing but a lazy outreach to a subculture that the production cast have previously glossed over) and his girlfriend may have the least interesting personality of them all.
But maybe now there's a character in Nick that I can care about following, and if they turned a class A **** like him around, maybe they can do it for the others. I would agree that the show seems to be going way too far into the characters' heads though, hopefully no one will go mental in this season.
