This "thriller" movie is full of arty photography and elliptical dialogue. Both are often without purpose. Aaron Eckhart plays an FBI agent in a professional death-spiral, teetering on the edge of sanity. Carrie-Anne Moss is woefully underused as his partner. Ben Kingsley plays someone who's gone over that sanity-edge thing, but he has pretty good reasons.
The key premise of the movie is literally unbelievable. It takes a real long time to get from beginning to end, and Aaron Eckhart's character spends lot of walking around looking at stuff and eating aspirin. Don't try watching this if you're sleepy. Or do, if you're needing to nap.
