The Uninvited

If anyone hasn't seen the trailer yet, it's here:

It's based on (but not totally a remake of, as I understand it) a Korean film called a Tale of Two Sisters. Mostly what I'm liking from the trailer is that it's more of a subtle psychological horror than a gory jump out at you kind of horror, and the former always sticks with me more. I also love Elizabeth Banks, and I remember really liking Emily Browning from the Lemony Snicket movie. Has anyone here seen the original Korean movie, or knows more about this film? It looks really good to me.
