What starts off as a slasher parody ends up as a zombie movie going through a morgue and Re-Animator phases. The first couple of minutes of Sexykiller are quite charming as a slasher threatens a campus. Early on we find out that the slasher is a girl named Barbara, a medical student. Her dog is names Jason- just one of the many horror movie references- and when the dog is run over, she grabs the driver and proceeds to tell us how she ended up being a killer. At that point things go downhill quickly. The parody is piled on exaggerated strokes, the cast starts breaking out in song, there are infomercial parodies, it goes on and on, we find out a bit about her childhood and teen years. Cops arrive to investigate the crimes. Two other students created a device to visualize people's dreams and also serves to show what a victim saw during their last minutes. They hope to be able to catch the killer that way.
Barbara and one of these guys fall in love but don't express it till later. Meanwhile, the guys realize that their device when used on the dead, brings them back to live and turns them into zombies. Throughout the movie no one realizes that Barbara, who is not all that subtle about her murderous inclination, is the killer. Fortunately the parody elements slowly fade away and the movie becomes more of a good comedy with serious horror elements.
Overall, the script is smart, the parody is not all funny though. It becomes a bit funnier once it settles for comedy. The movie is gory though, and if this crew would have gone for a straightforward horror movie or a mild horror comedy, they could created a pretty good movie.
