Ao Oni / Blue Demon (2014) (Blu-ray release 2014-12-10) is an adaptation of a Japanese survival horror game.  Basically a bunch of people are trapped in a mansion, and there is an ugly blue demon that chases people and eat them.  It feels like one of those forgettable generic low-budget horror movie.  I don’t feel any tension at all.  The ending is confusing.  I believe only fans of AKB48 (a member of which played a lead role in this movie) or the video game may check this out.
