I have to agree about John Carpenters "Vampires". Wasn't a horrible movie, wasn't the greatest either though. Think the major problem is that once Mr Carpenter puts his name on something people have some pretty high expectations for the movie, so anything short of awesome is a bit of a let down.

The worst horror movie that I can remember seeing has to be Halloween 3 : Season of the Witch. That movie blew goats. The worst part is that I haven't seen it in like 10 years, but still get that damn "Six more days till halloween, halloween, halloween. Six more days till halloween, halloween, halloween. Happy Costumes!" jingle that played throughout the movie stuck in my head.

Makes me want to pop out my eyeballs and scoop out my brains through the sockets with a spoon...
