In my opinion, this is by far John Carpenter's best film. Certainly his cleverest, wittiest, and downright enjoyable. Paying homage to both H P Lovecraft and Stephen King, it's a film where you can never predict what's going to happen, full of weird goings on, and lots of creepy, slimy monsters in dark places and people going mad. Sam Neill is excellent in the lead role, I think this is one of his best performances, and the mind-bending plot where you never know what's reality really gets under your skin. This is such an underrated film and I can't praise it enough. It's one of those films that gets inside your head and refuses to leave. I love nearly all of John Carpenter's movies, but this is by far his best, and the fact that it isn't even available in the UK on DVD is a crime. Worth buying on VHS, it's that good!
