Kyarakutâ

This is a reasonably good thriller, there are some good suspenseful scenes, the story is somewhat predictable but still interesting.

I can't speak about the dialogue because I watched it with english subs and they were probably not very accurate. And because of that I may have missed some point the script was trying to make, I don't know. For instance, the much-criticized ending maybe had some hidden meaning, some wordplay with the movie's title or something.

Acting was credible. Of course, there are cultural differences that will make some characters' reactions or dialogues seem odd. Nothing too serious, tho.

I think 6 is a fair rating, slightly above averange. Entertaining if you have nothing better to watch.
