After watching most of the recent action movies, I left the theatre with a headache brought on by incredibly tight/shaky shots and edits so fast that any hope of seeing anything is lost. This movie takes a step back from that. It isn't entirely devoid of those annoyances, but is much better than most. In fact, at times, you can even see a whole string of punches and blocks without a cut or a shake! Of course there is the inevitable wire work, that combined with the necessary special effects to allow Jet Li to fight himself. But for once there is an excuse other than "because we can".
The story is pretty simple. A murdering criminal is killing all the copies of himself in all the other "universes". Each time one dies the life force/resonant string thing, gets divided amoungst the survivors. Of course this leaves a ton of questions that aren't addressed at all in the movie, but I can live with that since those are more topics for debate after having fun at the movie. That is one of the strengths of the movie, the progressively more intense action. As the movie progress, rather than trying to deal with any question the viewer might have, the pace and intensity of the movie goes up. The final action sequence is probably ten minutes long all told, which, to me, is a sign of a true action movie, as opposed to movies with action.
Overall I give it a 8/10 for fans of the genre. If you aren't particularly interested in sci-fi/martial arts, especially if you have a problem with wire work and blue-screens, then you might want to skip it.
