30 great minutes crammed into an hour and a half

Jackie Chan's The Myth has two great action sequences and a couple of super-hot chicks...and that's about it. I've seen the original Chinese cut and I've seen the shorter US version, and my opinion of both is about the same--the longer version just has more dull stuff in between the sequences of cool stuff.
However, this movie has major story problems that have nothing to do with editing. The biggest story problem is that the most interesting, most fun character in the movie, an incredibly gorgeous kung fu fighting Hindu chick, well-played by Mallika Sherawat, is only on screen for about 12 minutes in both versions! The sequence she's featured in really works, as her natural comic style fits in with Jackie's slapstick action sequences very, very well. His character should have met her much earlier in the story and then she should have stayed with him throughout the rest of the adventure, adding more fun, a touch or romance, better story development, and some sex appeal.
A secondary story problem is that the "ancient China" sequences are slow and dull. I wish the US version had cut those parts down even more and given us a 1 hour 20 minute movie.
A third story problem is that the sci-fi/mystical elements of the story are, to be blunt about it, idiotic, resulting in dialog like "Science has proven that spinning an object extremely fast makes it lighter." Wha? I read Science Digest, and that's never been mentioned.

So, I think there is about 30 minutes total entertainment in this mess, but it is worth the time for the true Chan fan.
