Sinister is not a suitable title for this film. I’d say graphic is more appropriate. Or uncomfortable. It’s not particularly scary or important, it’s just some scenes of intense violence are not pleasant to witness. If it’s a good horror film you are looking for then I am afraid you have come to the wrong place. What you’ll find here is a splattering of modern horror cliches, complete with frustrating characters and a flimsy narrative. It relies on jump scares and graphic violence to produce tension but unfortunately it fails. Cheap tricks and bad writing are the true horror here.
