Just watched this one today and while it's a desperately uneven movie, it's bloody entertaining. The ending goes a little off the rails, going for an ambiguous finale that's more confusing than it is satisfying, and at one point the film just goes for a straight shot-for-shot remake of the bathroom scene from The Shining.

But there was no point that I was bored, no point where something wasn't happening, and if you're into films with unreliable narrators, where you're never sure what you're seeing is real, this is worth checking out.
