This is an intriguing film. Like Momento it requires patience and concentration. I think it deserves an oscar for the wry placing of the Beach Boys' "Good Vibrations" near the end of the film when Tom Cruise is in the building lobby near the end of the film.

I think I will remember this film for a long time. It is defintely a top 10 for 2001, but not a top 5.

Please, no spoilers on this film.
