Granted I only know of one other movie that fits into this genre and that is the Jim Carrey movie "Once Bitten". This one though is better than that one as it is just a bit funnier and has a better and more likable plot to it. This one has a teen going to the house of a girl for what he thinks is going to be a one night stand kind of thing, as it turns out though the person he is seeing is a vampire and he is soon infected and must now feast on blood. Thankfully, it does not have to be human blood as a rather friendly vampire teaches him the ways of living a rather nice existence as a vampire without having to drink the blood of humans. Unfortuanately, a sort of Van Helsing type hunter of vampires who saw him and his friend at the girl's house where he was bitten, however, he thinks it is the guy's friend and not him that has been bitten and turned into a vampire. The guy also is having girl trouble as he even tries to use vampire hypnotism to get the girl he likes. All this makes for an very funny comedy that really is rather lighthearted. So while not perfect, it makes for a fun film to watch.
