I dunno what the hell Aphex and exp are talking about but that movie rocked ass....
Denzel did a GREAT job, and Ethan Hawke was equally convincing, I'll admit that the first time I saw it I felt the end was sort of unreal, but the second (and on) time I saw it it kinda meshed as being surreal for a reason, it's supposed to be a BAD area, it's supposed to be the type of place where you can get shot and nobody would ever know. And I think they did a good job portraying it all. Plus the twists and plot development were good.
I don't know anyone who did not like it.
