It is unusual for me to like this kind of movie. They usually get me bored. It is slow, yes. An it has just small amount of jump-scares. It is for me most like Supernatural Thriller than Terror, I found it a good exercise in suspense built with paranormal dyes, needless to say with psychological dyes or para-psychological. Convincing performances must say, except for "Parker" whom I found something bland, but he is supposed to be ... I think. Now, "Rebecca" was less than nothing, in what she is seen, only her voice convince me of something (when you see it you will know what I mean). The end worth the movie, really , especially for the effects, I liked that part. Surely some (as I did) will find something "illogical" in the actions of the character at the end (I had run, and you will realize what I mean) and the post- credit scene, apart from not being strong, it's a little useless there. I give it 7.5 / 10, for some things I did not like and that could be polished, but would be 8/10, and I repeat that I liked the end. See the movie and rate it (or do not see it if you hope horror o more action and gore)
