Ah yes - Dark Water - very creepy, and at times matches the Ring for atmosphere.  U.S. remake was okay too I thought.  Ring is just amazing isn't it.  I recall when I first watched it was alone in flat one Sunday evening, dark and raining outside, flatmates away for the weekend... v. freaky. I really liked the U.S. remake of Ring too. Audition is on a whole other level of ouch though.  A genuine shocker of a horror movie. Have you seen Shutter?  It's a Thai horror flick but there's a semi-decent U.S. remake too.  I heard that Mother is quite bleak but also has some very decent reviews.
