Once again, I'm in the minority. I thought this movie was incredible, beyond the evident manifest artistic display that it is but also the twisted and eminently psychotic world of a serial killer. I suspect the shocking scene of the horse being sectioned off into a dozen pulsing, breathing pieces was responsible for putting a lot of people off, but that's tough. If it didn't put you off, you might be interested in:
