I wouldn't classify it as full on horror movie.. It will fall into the category of thriller, mystery genre. Creepy is the word you will associate for some scenes. I went into the movie with low xpectations since my last horror movie "The Nun" was a disaster. I don't think movie disappointed me. Sure the story is very old and you will see some usual shenanigans and cliches for this type of stories. Taylor schilling is decent and the kid acted really well. There are 2-3 jump scares but overall this is a decent one time watch . I liked climax and was a worthy ending to story. 7/10 for me.
