Bitten never manages to strike a balance between being a serious drama about a codependent relationship with a vampire, and being a comedy. There are some truly awful music choices, and any humor here falls flat, and even if i could see where this would work as a dark comedy, it shifts gears back to being deadly serious right after. I didn't realize Mewes was in this until I was already watching it; he does an okay job here, but needed a better directer to guide his performance. Erica Cox is easily the best part of the movie: her acting is good, and she keeps a steady tone throughout, despite the chaos; furthermore, she is gorgeous, and in various levels of undress herein.
I would have enjoyed Bitten more if it fully committed to being either a dark love story about falling in love with a woman who needs to murder people in order to live, or being a silly romantic comedy.
