Query: great potential, poor realization

This movie is a great disappointment. With interesting plot and deep philosophical message, it could have been a great movie. Unfortunately for the viewer, this promising set up has been turned into a boring crimi with unclear purpose. On top of everything, both main actors' performance (B. Willis and S.L. Jackson) fell behind their usual qualities. Avoid this one unless you are a diehard fan of one of the two main actors!
