I don't know what to make of 'Otogiriso'. It was slow from start to finish, quite a feat for a movie that runs less than 90 minutes, but it built up a strange and creepy atmosphere and was crafted using some interesting concepts.
I can't say much about the plot without spoiling it: Nami (Megumi Okina) has been designing a video game based on dreams she has been having. After finding the house from her dream, Nami and Kohei (Yoichiro Saito), decide to investigate the house. Naturally, this is a bad idea, but video games and movies alike thrive on bad ideas.
The whole concept of 'Otogiriso' is that the movie is a video game. It plays out like a game - the characters are stuck in one location, they have a support team they can phone, they have maps and must find keys for locked doors. A nice idea, but probably one that would appeal to gamers and few other people. Others might appreciate the cinematography, but this is definitely not for everyone.
'Otogiriso' is a good movie, I would recommend it to gamers, and maybe fans of Asian horror movies - 7/10
