I love Evil Dead. I think it's better than Evil Dead 2, which was basically the same movie redone with a budget.
If you want more Bruce Campbell (and how could you not?) I'd recommend Army of Darkness next.
I watched Blacula tonight. I hadn't ever seen it before, but it was fantastic. Not even slightly scary, but the whole 70's vibe was hilarious. And why does he grow extra facial hair when his vamp teeth come out?
It's like he was part werewolf too.
I've been trying to think of the name of a movie I saw last year that really scared me. I've finally remembered (with the help of imdb) -- it was The Grudge (the original Japanese version, not the US remake). It's about a haunted house, and it was definitely the scariest thing I've seen in years. One scene in particular gave me nightmares. I'd recommend it to anyone who really wants to be terrified.
