It's a Speghetti Western with fangs.
It was about when I saw Lucy Liu wearing a poncho in this movie when I suddenly realized that this was current-day, vampirized version of a revenge western. The beautiful Lucy Liu gets turned into a vampire, she gets up and decides to take revenge on those that turned her undead. She even gets mixed up with a sherriff (Chiklis) who later joins forces with her. Instead of a sideiron she uses a crossbow. A vampire version of a Clint Eastwood movie with a hot, Asian, female gunslinger sounds cool on paper. But its mostly pretty boring.
What might give it a reason to rent is that you can see Lucy's boobies. And Marylin Manson and Nick Lachey have small roles in the movie.
