Twas original. I really didn't expected anything like that. But... All these acidic colors and enormous numbers of effects is really annoying. Violence is too schematic (especially death animations of grunts. Looks like they all have ste same animation of dying). All this is more suitable for game, but not for movie. Music is also not very good for this sort of movie.
And yep. Moment of killing two groups of swordsmans was incredibly stupid.
Overall good, heh.
