Yeah, I saw it.
The movie is a strange mix of American gore/monster movies and Japanese animation. It's really somewhere between Japanese and American cultures, no wonder the story takes place in that particular context. ^^;
The plot is... "simple". ^_^;
Don't expect any thought-provoking ideas. It's just an animated action movie, nothing more.
Some really impressive action scenes, and a good use of CG overall, in my humble opinion.
The design... Well, it's Terada Katsuya, so you can't say that the guy can't draw. ;D
The English voice acting is... Er... Well, some characters reminded me of Bio Hazard, sometimes, and that's not exacty a good thing. But it's not that big a problem.
There is (fine) Japanese voice acting as well, but not as much.
Too bad it really looks like some kind of a "pilot". The movie introduces the main character and "her world" and that's about all. Of course, there are novels and videogames, but still...
