Didn't make sense (SPOILERS)
-- SPOILER ALERT !
I found it really, really weird that Ray Liotta's character never told Jeff's wife about the infidelity with his own wife. Especially after it became clear that A) he wasn't getting any money from Jeff and B) he and Rebecca was splitting up. I think most people would -- even if they weren't particularly vengeful.
Yeah I know, they tried to address that with his little speech on the bridge about him "not being a guy like that". But that doesn't make sense, seeing as he just tried to squeeze 100 K out of Jeff over it. At least IMO. Did anyone else find that a bit unbelievable?
