Good: The Hills Have Eyes - Tight low budget horror film that stretches every dollar perfectly. They basically used a trailer, the desert and instead of makeup effects they hired a guy who has a real-life medical issue (though I feel bad now that I know that). For me a big part of the horror was that the people being killed weren't random teenagers; they were family members so nobody felt expendable.
Bad: A Nightmare on Elm Street - The series is a childhood favorite but hasn't carried over into adulthood well. I'd always considered the first to be very dark and serious, but when I returned to it a few years back I thought it was garbage. I'm afraid to rewatch my favorite, Dream Warriors. The Dream Master was my first ever horror movie so it holds a special place for me, but I know better than to retry that one.
Ugly: Vampire in Brooklyn - Haven't seen it since it first came out, but a failure on all levels, and the beginning of the end of Eddie Murphy.
+1. this is very interesting.
