There's not much I can say for this movie other than it is evident that I rented the wrong movie. I had in my hands Marebito and A Tale of Two Sisters. I put the latter back. Now I regret it.
This film started out relatively creepy. Then it took some path that I just wasn't following. Man is obsessed with fear. Man goes into tunnel. Tunnel suddenly looks not unlike Genesis in Star Trek III. Man finds naked woman chained. Man somehow gets out of bizarro tunnel with naked woman and puts her in his apt. Naked woman doesn't eat food. Naked woman likes blood. It became some weird vampire experience with oddly sexual/animalistic blood drinking scenes. What I can't understand is why the guy didn't slice his wang and let her lick that, as he was obviously getting off by her licking his hand. Pervo.
About 3/4 of the way through, I fell asleep. And I have no idea what happened.
