Psychosis or Reality, scary nevertheless!

Rating: 8/10 (3 July 2019)

It's astounding, how well developed the movie's horror is. It starts with the childish imaginary terrors that the son of the protagonist suffers from at night. Whenever the son cannot sleep, the mother (the main character) soothes him and reads to him until he's back in the realm of dreams.
One evening, the son had a nightmare again and the mother let him choose the book, which she reads to him; it's called 'Mister Babadook'. At first, it looks like a beautifully drawn childrens book, but it quickly turns out to be anything but that. The son is genuinely terrified by it and even the mother is apprehensive.
A couple days later, the mother destroys and throws the book in the trash bin, but finds it, just the next day, lying in front of her home's door - the pages that she destroyed glued together. And from here on, the real terror starts.
The son claims again and again that he had encounters with the babadook in his bedroom and the mother hears strange noises and has visions of the clawed monster as well. The babadook grows in power until he is nearly omnipresent. After a heavy, terrifying fight against the babadook, which is the climax of movie, the mother and the son manage to lock the powerful monster in the home's basement, which makes it his life prison.
What also is really well done, is the fact that it's - for the most part of the film - not easy to say, if the events are just psychotic experiences of the mother and her son or if it's really happening. It's interesting to be left constantly doubting the films reality.
