Blood: The Last Vampire

If this film didn't exist someone would have to make it. In the first reel we witness our heroine Saya slay a man on a subway. She's a teen vampire hunter and the secret org she belongs to not only stalks the blood suckers but has a team that disposes of the ensuing mayhem, blood and bodies. Before long Saya, who's a perpetual 16 year old, is given the assignment to track down vampires that are hiding in disguise at an American military base.
Before you can count musical cues that include Edwin Starr's "War" and Deep Purple's "Space Truckin'" Saya has enrolled at the base high school and finds herself immediately drawn into battle. Saya does her ass kicking with a samurai sword and director Chris Nahon (Kiss of the Dragon) unleashes martial arts staging for many of the face offs. In fact one of the battles reminds viewers of the scene in Kiss of the Dragon where Jet Li fights like 100 bad guys at once. Only here Saya slashes wildly and Nahon offers uncertain continuity enhanced with lots of digital blood. Much of the time the blood flows in slow motion and looks like someone ripped open a bag of leaves.
Blood: The Last Vampire is based on a short anime film that itself spawned a short lived magna television series. This live action film is set in Tokyo during the mid-60s. The covert org that Saya belongs to has cleaners that pose as CIA agents and that brings them into conflict with the base general whose daughter's life was saved early on by Saya.
There's also some flashbacks to a feudal era but this diversion stalls the story rather than enhancing. More exciting is Saya's confrontation with the "patriarch of all vampires" and a couple of sequences that involve chases over rooftops as well as a confrontation with the evil patriarch, who transforms into a kind of alien type claymation creature.
Blood: The Last Vampire is designed to please its core horror audience but might also be of interest to newbies who liked Twilight and want something with a little more bite.
