Mama (Blu-ray release 2013-5-7) has one of the better stories among Western horror movies I’ve watched recently.  As the title suggests, you get a ghostly mama taking care of girls.  Although having little scares in the central part of the movie, it keeps me interested in the story.  Mama is not shown clearly until the final act, in which not everything occurs reasonably (although this is unfortunately generally true in horror movies).  The ending is unique – whether it is a positive ending or not depends on the viewer’s perspective.
