Personal enjoyment of this was probably more a 4/5, but I realize it had its faults. But I love these low budget Japanese sci-fi/action/horror flicks, there's just something about them that always entertains me. Even the CGI blood I can forgive, because it's kind of part of these films' charm. It's certainly an acquired taste, but if you like films such as Machine Girl and Meatball Machine, this should be to your liking. Tons of great action sequences, sexy ladies, zombies, gore, explosions, boob guns... what's not to like? Yeah, the story isn't the most developed, and its all a little silly, but I had a blast with it and thought it was a super fun, exploitive take on the 009 series.
