Nothing But Blackened Teeth

I don't know what this is. It's not good enough for three stars because there was so much that bothered me, but I read books I rated two stars that were worse.
The idea/concept of the story is great, however it laked something... What bothered me most was the attempt at a japanese atmosphere that didn't work for me but confused me. Though with a degree in japanese studies I'm probably more critical (especially in the use and presentation of Japanese language and culture) than a common reader without this background.

I believe this might make a good movie IF it would focus even more on the stereotypes of horror movies, but the ending too abrupt...
