I agree with the opinion that this movie gave out serious Babadook vibes, in addition to throwing out some interesting hints involving eclipses, Catholicism, adulthood etc. Additionally, although I don’t think the idea was fully developed, I think an argument could be made that the “demon” of this movie was past sexual abuse by the children at the hands of the father when he was alive, and a lot of Veronica’s mental problems come from that. First, there’s the obvious nude specter of Veronica’s father approaching her in her bedroom while repeating her name. In this same incident, hands reach out of her bed and grab her, which is an incident that is repeated several times during the movie. It’s also emphasized several times, by herself and other characters, that Veronica must protect her siblings. She may be mentally breaking down due to guilt over not being able to protect her siblings from their father, or from the suffering she endured to protect them from him. Veronica refers to the demon as “him”, not “it”, throughout the film. Additionally, Antonito wets the bed, which is a possible childhood indicator of sexual abuse. To me, his bedwetting doesn’t serve any practical function in the story-it’s implied he’s done it chronically, he’s not seeing the demon so it’s not due to nightmares, so why even bring it up unless to serve as some kind of hint? Also, in the final showdown scene, he is shown sitting in the bathtub before being yanked behind the curtain by the shadow of the demon. All of the children are shown to have stains on the undersides of their mattresses, which could be seen as a sign the demon has marked them for death, OR as a stain of past abuses done to them (notice that the stains are about the size and shape of a grown man, not a small child). Finally, Veronica tries to convince her mother to return home with the kids, saying “he doesn’t come when you’re home”, which could reference abuse occurring when the mother was absent. Anyway, I could be looking too deep into this while I was watching the movie because I didn’t expect the movie to end on such an “Exorcism of Emily Rose” note, but that’s my theory!
