The intro for this movie, with the "blood rave" scenes and the first battle, has got to be one of the best openings for an action movie ever made!

A Nit, though...
Towards the end of the "blood bath" fight, Blade uses the tip of the sword to make a line for the bad guys to cross over. When he first puts the tip down, it's on his right, but in the next shot it's on his left (and there is no sound to indicate he moved it).
