I just watched this movie too, and it wasn't that bad. It was a lot better than some of the cross-over films. I don't know if anyone is still interested in talking abou tit, but tactics aside (It's a hollywood movie - everyone shoots from the hip), it was a decent action flick. BHD is probably one of the few movies that had realistic battle scenes, and this movie can't compare in those terems....I mean, c'mon, a hand held mini-gun?
I thought the sword fight was okay. It sort a pays tribute to the original, when what's-his-nuts stays behind, drops his tac-vest and tries to have a knife fight with the predator. The sword fight scene could definitely have seen improvement(the yakuza should have been portrayed as a bit more skilled with the sword - wait for the pred to attack, rather than swinging wildly like a person who's never picked up a sword), but casting realism aside, it was cool that it was in the movie at all.
