I think they have chemistry too, so I don't understand why some reviewers have said otherwise. Their characters were mostly self-absorbed by their own issues for most of the show, so they wouldn't really look at each other that way... nor did they trust each other... but they've each had to face up to their issues recently and basically scan as broken people fighting to stay alive (psychologically as well as physically).Second the Awww..damn. Everything is making sense now. I love Rachel McAdams in this. I liked her before but I think she is wonderful in this. And I think she and Colin Farrell do have chemistry, regardless of what I keep reading. Vince Vaughan - the more fucked up Frank is the better, imo.
I think Vaughn has done really well when Frank is DOING something, versus just standing around trying to deliver crazy lines believably. Frank's a doer. His scene with Blake was riveting because I wasn't sure what he would do next; and the same with the Russians who came into his bar. You know he's capable of nastiness, you just don't know when he'll strike.
Crazy scene with Davis (?) too.
