Query: This is a keeper.

It's amazing what one can find in a subway tunnel, or the evil that lurks there. This was a surprize for me. I was looking over the imports and thought the title sounded interesting. Yes, it is. With out giving too much away, this is a good ghost story, told only like the Japanese can tell it. I'm sure, there's some American company shooting their version now, but see this before the remake.
