The acting and casting are terrible. Alyssa doesn't do too badly, but doesn't really have all that many lines. She's mostly expected to look like she's enjoying the erotic scenes, then look confused in all of the other scenes. The best scene in the movie is Milano's encounter with the photographer.
There's a lot of cheesy, annoying voiceover by the vampire to substitute for plot, story and character development. His acting is the worst in the movie.
Overall, the only reason to see this movie is to see Milano nude. Other than that, there is nothing else compelling about this film.
