Saw it on Netflix awhile back (no longer available on instant). It instantly became one of my favorite horror movies of all time, and I REALLY mean that. It is very underrated. Either you will love it or hate it, but watch it at night with the lights out and give it a chance.

They are actually remaking it now in the United States (original is Australian). I live in the U.S. but I wish they had just left it alone. It is already a masterpiece in my mind.
