I'm just going to take pieces of a review that basically sum up everything I have to say about this crappy movie:
"Let's not pretend why you watched this movie. I defy ANYONE to show me a movie that can't be improved by a cute Japanese girl dressed in little more than her underwear, a feather boa, and cowboy hat...with katanas. Yeah, I'm pretty sure if they'd thrown a character like that into Citizen Kane I might just agree with all those people who say it's the best movie ever made (it's not). And if said Japanese girl is, let's just say "well built", then all the better. So how bad does a movie have to be that all of this eye candy can't even save it? I don't know, but the Onechanbara sequel figured it out.
The plot is basically watching the lead "actress" jiggle and fight her way through hoards of zombies. I know that sounds like epic fun, but it's just not in this case. When a buxom Asian girl killing zombies with samurai swords cannot hold my attention, something is very, very wrong. I also cannot underestimate how annoying the whole "blood spatter on the camera" gets in this movie. Use it once or twice for effect...that's fine. But, if memory serves, it happens in EVERY fight scene in this movie and usually more than once. The whole thing is just a mess that not even your (and my) rather juvenile male desire for ridiculous amounts of eye candy can make excuses for."
