I just watched Fright Night. One of those troubled teens 80s flicks. The boy wants to bang his virgin girlfriend but she's not ready. Then when she is ready he notices a vampire move in next door. She gets mad and stops talking to him. When local hookers start dying with their heads cut off, the boy tries to warn people around him there's a vampire next door, but of course no one believes him. So he turns to Peter Vincent, an homage to horror host Larry Vincent, who just got fired because nobody wants to see vampire flicks (the scene was spoofed in the new Frankenweenie movie, I swear!). Worried about her boyfriend's sanity, the girl asks Mr. Vincent to prove her boyfriend's neighbor isn't a vampire. Things go well at first and the boy promises to leave his neighbor alone until Mr. Vincent notices the neighbor lacks a reflection and beats a hasty retreat. Now certain that he's not going crazy, the boy renews his efforts to kill his neighbor, but things go awry when the vampire turns the boy's bullied friend into a werewolf and tasks him with killing Mr. Vincent. (Oddly the cross works on the werewolf even though at that point of the movie Mr. Vincent lacks faith.) The girl gets abducted by the vampire and he turns her into a vampiress. In a race against time, the boy and Mr. Vincent enter the vampire's home to kill him. Full of great 80s schlock special effects. The head vampire's death scene was pretty cool, I thought. Not as good as the ghost in Sweet Home, but still cool.
Just saying, if you're not a big horror buff, there's something to be said for the 80s troubled teen vampire movies. I like them, personally. Maybe the tropes make it enjoyable for me. One of the few times cliches are good things.
