THE BROOD meets GARGOYLES?

That's how this movie felt to me, somewhat of an hybrid between those two horror movies from the 1970s (1979 and 1974 respectively).

For me it was definitely more entertaining and powerful than the other similar (maybe only in setting) Blumhouse movie THE DARKNESS. Maybe because I connected with TCK due to being grieving since 2019 when I lost someone that I loved, like the family in TCK.

After I finished watching it, I went to the web to try to find an interpretation/explanation of what the entities were, but only found negative reviews and prima donism from watchers, people that just want more of the same and can't digest a little horror arthouse.

Then it did hit me, it's arthouse, and the elements that aren't explained are precisely there for watchers to arrive to their own interpreations.

--- spoilers below ---

I am not going to complain about how the part when the father goes looking for a signal, to call AAA, and he finds the corpse doesn't make sense. Or why the creepy entities aren't explained.

Precisely that scene, the one when he finds the corpse, is a trigger that sends your intellect on a tailspin and makes it come up with all sort of creepy reasons why the dead guy did end himself with a pair of scissors, or how the childish doodles fit into the story, or what the entities are.

If you have a modicum of a horror-genre-oriented imagination you can figure out at least several interpretations.

For one thing, the similaraties of what Nathan founds in the trailer with the corpse to what is actually happening to him and his daughters, and his conclusion about what the entities wanted should give you a vague outline of what is happening, and what happened to the corpse.

A) You can see the abandoned trailer and the corpse as people in a similar situation to the three protagonists but that didn't survive the ordeal

B) You can take that whole scene as a hallucination of Nathan's

C) ... (I ran out of ideas).
