The story initally did not show where and what it Intendedd to do. But it got interesting, following the Edward Norton character piecing the puzzle pieces together. Despot the physical handicap portrayed in the story made it more compelling to watch.
Best of all for me, was the music, that reminded me of Mile Davis influence, not only in the performance by the musicians, but the background as well.
I might even look for the soundtrack album of the movie, if it is available.
