As much as I love horror movies, a dominant portion of them do not have complete and sensible plot, character development, closure, and/or internal consistency.  陀地驅魔人 (Keeper of Darkness) (Blu-ray release 2016-4-14) surprisingly has none of these issues.  The protagonist in this Hong Kong movie is able to see ghosts, and uses this ability to perform exorcism – not using a Catholic cross (as we’ve seen a lot from Hollywood movies) but something else.  It combines both real Chinese traditions and fictional inventions in a rich story that feels really new instead of repeating some previous movies.
