Oliver Stone is a good director.
As good as Eric B's performance in this movie is, the camera work is right up there with him. The scene where the druggies pulls out the camera is so well done. And the ending monologue, with the camera spinning around, showing Eric B's isolation is also masterfully done.
I bet if I watched it with the sole intent of looking for interesting camera work, I would find a few more things worth discussing here. But those two scenes I mention in the first paragraph are what make me have such a high opinion of him.
