Interesting idea but not conveyed all that well. It was confusing at times and some of the music was intrusive. However, Willis was good and Pitt was great, particularly at the beginning.

Pitt is a very convincing mental patient, and Willis pulls off desperate extremely well. Unfortunately, there were some problems with the time shift and that pesky paradox, but other than that I enjoyed this one. Plenty of action, a twist or two, and a good tale. Worth watching.
