Horror with a very interesting idea and extremely poor implementation. The first half of the film looks in one breath. It is interesting to understand what is happening, and there are practically no plot holes and blunders (well, except for the brilliant decision to pull the switch, standing knee-deep in the water).
In the middle, the film begins to turn into a farce. The case with the sister of the main character opens the way to a series of completely inadequate actions on his part (in general, even he himself realizes this), the behavior and motivation of the fuck are also incomprehensible, and the ending with this turn raises more questions than it gives answers, and finally destroys the inner logic of the world.
Classic, it is worth seeing, but miracles to wait - no.
