A dark song is a cerebral dark occultist tale with a horror element.In this movie a determined young woman and a damaged occultist risk their lives and souls to perform a dangerous ritual that will grant them what they want. A Dark Song you can praised as one of the best horror films of 2017 which is a thoughtful grounded take on the search for meaning that mixes horror conventions with things still darker yet which strains towards a transcendental moment which a lesser filmmaker would have been afraid to contemplate.However the ending was little bit disappointing but overall a good horror film to watch from a long time.
