The original or the remake?
The remake has jennifer connely I think who is hot as hell. I have seen the original sitting in the viseo store but have yet to try it because haunted water does not seem too interesting. I wish the japanese (chinese and koreans) would get off the ghost kick and try some serial killer and monster stuff again.

As far as bad guy goes- what I said about it is pretty much all there is to it- it is a character study of the titular scumbag and his prisoner. It is interesting because the guy is such a bad guy and yet their is some good in him....sorta.
