For me a movie I just saw that really blew me away in the badness x enjoyablity factor.
Sleepwalkers
Cat/vampire people who are afraid of cats. Cats hate 'em and they kill 'em.
Mother/son have an incestual relationship.
Also has Madchen Amick who I had never heard of before but she stole my heart.
Great death scenes and has the chubby guy from Beetlejuice. You know the one! He plays a teacher.
The ending which is incredible but maybe for such a classic you want to be surprised the first time you watch it so CAREFUL!
