Really interesting movie. It's creepy when you know someone is coming for you, and you can't stop it. The only thing you can do is run away and hope you survive long enough. The only thing I don't understand is why this curse is transfered during sex, but that's just a small thing.
I would recommend this movie to everyone who's looking for a creepy horror-ish movie, because the movie really set the right atmosphere and has some good music to go with it.
