Regression (Blu-ray release 2016-2-1) is about satanic ritual abuse.  The case starts with a 17-year old girl claiming she was molested by her father, although he does not remember doing it.  Through regression hypnosis we witness satanic rituals, and gradually even the detective feels the presence of evil.  Before the ending, it is not bad.  Then everything falls apart.  Too bad.  In general I do not appreciate a movie that rejects itself.
