What an exceptionally dark, and very compelling movie. Joaquin Phoenix gave me this very creepy ,very Javier Bardem from Old Country feel. He was very quiet, and calculated, choosing a ball peen hammer instead of an air tank as his weapon, but no less striking and scary in its action.
While there was points in the movie that felt very untold and twisted around, it plays through properly from Joe's standpoint. He's losing his grasp of reality slowly and trying to offset the decline of his mind with pills, which it seems only serve to accelerate the pain and disconnection from reality. For those that say this movie isn't worth the rental cost. I have no idea what movie you watched, or what you were expecting from it. But to downplay the performance is doing a disservice to Phoenix performance.
While the content is dark, its a wonderful story and it shines a light on a very real darkness in our world that needs to have its images brought forward and slammed into your mind.
