I did not figure out what the point of this film was. In my mind the mother was harboring a lot of demons in her mind for various reason and was also very prone to react to suggestible prompts from the outside world, especially her son's' own fears. I did not find it satisfying and hated the fact that there was no conclusion or ending to the story --at least, none that I could discern.
Started off strong but got a little bogged down as it went along. Almost like a soap-opera in some ways when it came to what happened, when, to whom. Ending is unclear --intentionally, I am sure. Hate that!
