I believe mother! Is an incredible movie, even though the story isn't as unique and unpredictable as some other horror movie it is still full of suspense and good Gore that makes the movie the horror that it really is.
When I went to the cinema to watch this movie everybody was genuinely shocked and frightened by the movie, a scene I'll never forget is when the husband takes the baby and allows everyone of his followers 'praise' it, followed by the baby being eaten and the mother being beaten up, everyone's reactions were exhilarating and I think that really shows how good of a movie that was, it live up to the horror and thriller that I was meant to be.
