I actually like Frank, that whole pillow-talk bit about being locked up in the cellar by his father and everything being paper mache really got to me. His whole story arc is like a thesis on "maslow's hierarchy of needs": He was coming clean and seemed almost kind, in a weird evil way. But he is again going bad out of desperation for all that he has lost and needs to rebuild, and it is all reflected by his relationship with those around him (specially his wife). I am looking forward to see how far he goes to get it all back, and how much it will cost him.
The guy I can't stand, honestly, is Paul (the bike cop). The scars and sexual-orientation angst suggest he had it super rough when he was younger. But it feels a bit too silly how seriously he takes it when everyone else doesn't. Seems like he is fooling no one but himself, everyone just rolls their eyes at his act and I don't know how much longer they can keep that up without getting too frustrating. I'm hoping he just gets laid soon and is liberated, not sure where else that could go.
It does seem that the dialogue is a bit redundant or too explicit at times. Like how Ani's dad replies "I just did" when told to speak with his daughter. Or the gay dude at the bar saying he can be with women "in a pinch and with the right medication" (a callback to Paul's shower scene in the first episode), etc. But I guess some people may watch it without paying too much attention, and need those fallbacks?
