Michael Shannon
This guy is a brilliant actor and was on the level of a Deniro in his heyday in this film. Shannon, just like Deniro had all the head, facial and eye movements that make a great performace, especially in a crime flick.
Ive read some stuff on the real life Kuklinski and theres a lot of different stories about him and was he really as bad as he says he was. So i dont know if this guy was a real gangster or or not.....what i do know is Michael Shannon took this role and made us know without a doubt that he can play a gangster and do it as good as any of the other actors known for gangster movie.
With that said, I would give the movie a 5 out of 10 but I bump it up 2 points for Shannon's performance. Thats how good he was imo....good enough to turn an average movie into a good one.
