Decided to check this out because it was a sort of cute premise and was directed by someone who worked on Xena. It's actually rather similar to Xena, with the same goofy humor, obliviousness to accuracy and general good-heartedness, although the good-heartedness is push a little more because it's for the Disney Channel. The fight scenes are fun, the movie has a good sense of humor and it's a nice take on the Buffy the Vampire slayer story. In fact, while the Buffy movie had a clever idea (shallow popular girl has a destiny) it actually wasn't a very good movie, and between the two I would take Wendy Wu. Definitely worth watching.
