Ma is the most suspenseful and scariest film I've seen this year. Octavia Spencer killed it as the title character and did a great job playing such a villainous role. This film is about a lonely woman who lets a group of teenagers use her basement as a party spot and she is not what the teenagers think she is. Very predictable but good. The most original horror film I've seen this year since Us. Not bad for a psychological horror film.  I give this movie 4 out of 5 stars and a huge snap. Highly recommended for those who love great horror thrillers.
