I dont know how people get such crazy, hi funda ideas. The storyline is literally unbelievable. Anyway kudos to the director for thinking different (too different I must say). He bring in the concept of multiple universes (multiverse as he calls it). The multiverse Jet Li tries to kill his counterparts/ lookalikes in all the universes so that he could gain more and more power. Only one more Jet Li is left and the bad Jet Li loses to this good Jet Li.
The animation sequences are too good. One such scene is where Li bangs a cop with two motorbikes. There are many such good shots. The climax fight sequence is also great. The movie is definitely watchable.
