What's the worst horror movie you've ever seen?

A Sound of Thunder is indeed one of the worst 'real' movies ever made. It's bad to a point that it's absolutely a favorite amongst some of my friends. We still quote some of the shockingly absurd dialogue to this day. The fact that real actors are in something that looks so cheap and horrible makes it that much funnier.

I don't know that it was trying to be a horror movie really, but it's stunningly terrible.
