What a waste of a good build-up

Rating: 4/10 (21 June 2018)

I went into this without having read any reviews - only the major headlines from critics saying how wonderful it was. I'm was in agreement for the first 1 hour and 50 minutes. Sadly the remainder of the film was dire.
I loved the build up and suspense. It was well-acted and the dark foreboding with very few jump scares was a refreshing change from the usual standard.
Then we get towards the end and the film descends into the usual standard of horror films. The revelation at the end didn't make any sense in the context of how Paul, the boy, was treated in the lead-up. It seemed as though the script writers, having done an excellent job of building up tension, suddenly realised they didn't have an ending and so cobbled one together so as to get their pay-cheque.
Perhaps they should have cut the film at the flower-bed scene and saved us the big "explanation" at the end?
All in all a big disappointment.
So out of 10 stars which I would have given it: 4 off for the awful ending and 2 off for the retrospective nonsensical treatment of the characters once you know what the ending is.
