WMG / The House (2022)

The movie is about Character Development... for the house itself.

In the first story, it's freshly built by a wealthy cruel asshole to torture and break a poor family, and it does so, but witnesses the sacrifice the parents make to save their children, which is not guaranteed, given the harsh weather they're driven into. In the second story, it's a fixer upper, whose purpose is done, and hasn't been taken care of for a long time in current day, and for the first part of it nothing concerning begins to happen until it becomes evident the Contractor is cutting corners and fixing things on a surface level, after which, after it's obvious no one will stay, it makes its own occupants out of insects, who destroy what The Contractor did fix. Lastly in the third story, the focus shifts more on Rosa, who wants to actually fix the house and see its potential as a happier home for not only the tenants, but eventually her to have happy memories. It witnesses her planning the repairs, wanting rent to make genuine fixes, her honest conversations, and her fear of moving forward pushing the closest people in her life away - to the point of allowing a stranger to make huge changes to its structure and use its material to save the tenants. It eventually gives her visions after she accidentally falls into the flooded basement to show her what she and it will actually stand to lose, transporting her to the tent to make sure she sees Jen leaving and understands. She does, and by trusting the changes made to the house, dislodges it and saves both of them from losing everything to the floodwaters.

Uncle Lucien is one of Van Schoonbeek's men.

Uncle Lucien, like Van Schoonbeek's workers, never speaks aside from a few groans and barely even moves. Van Schoonbeek might have inserted him into the family as The Mole to single out any potential targets like Raymond (and implicitly Raymond's father). They also share the same Voice Actor.

Rosa lost her family in the floodings.

The second story features a form of reincarnation.

Evidence to this lies in how the Odd Couple explain that them and their family used to live in the house, yet the only other creatures we see in the house aside from the Developer are the bugs, and the Odd Couple/Family are clearly giant versions of these bugs in disguise. And some of these bugs were killed by the Developer with poison. It's entirely possible the house in fact resurrected these slain bugs as the Odd people, hence their desire to continue squatting in it and why there is a clear connection between them and the bugs.

It's also possible the Developer fell prey to this resurrection as well. After all, he inhales a big dose of poison which sends him to the hospital, and being collected by the Odd Couple can be reflective of the possibility he in fact died and being resurrected by the house is what converted him to his feral state.

Was the Developer hallucinating the Odd Couple?

Given that the Odd Couple show up around when the viewing goes south for the Developer, did his mind just create them as a response for his anxiety? Nobody else seems to notice them beside the Developer, and when the latter is talking to the police, they don't make any notice of them.

It's also implied that the Odd Couple taking him from the hospital and the other bugs was just him dreaming while in a catatonic state.

The entirety of "Part II: Then Lost is Truth That Can't Be Won" is a direct allegory for the main character's ambiguous mental illness.

• The House itself represents the state of The Developer's mind.
• The constant calls from the bank represents severe stressors in his life excacerbated by the unhealthy state of his mind.
• The Fur Beetles (which have been there even before the renovations,) represent The Developer's mental illness and the progression thereof.
• The Developer's insistence on doing everything himself represents a stigma against seeking mental health assistance.
• The people who would otherwise be renovating The House (carpenters who could have spotted the infestation early on, and exterminators who would know how to deal with it,) represent mental health professionals.
• The Developer looking up how to deal with a Fur Beetle infestation online represents looking up how to self-medicate for a mental illness.
• The bug poison represents medication—most likely drugs rather than anything prescription—without prescription from or oversight by a professional.
• The house showing represents enduring other people while internally falling apart, and putting on a crack-filled and surface-deep appearance of put-togetherness.
• The Bug Couple's appearance represents the beginning of a mental breakdown.
• Their squatting represents the further deterioration of The Developer's mental health.
• His initial willingness to go along with it in the hopes that everything will turn out okay represents his denial that things are getting worse.
• His harassment of his Dentist represents the symptoms of his mental illness which are visible to others.
• His calling the Police only for them to confront him about his harassment represents societal overlook of the root cause of severe social transgressions and ignoring that those who commit offenses may be in dire need of help themselves.
• The moving-in of the Bug Couple's extended family represents a catastrophic decline of mental stability that The Developer can no longer ignore.
• His attempt to kill them with the poison, only to poison himself, represents his desperation to make it all better, only to overdose on whatever he uses to self-medicate.
• The Bug Couple picking him up from the hospital represents the failure of medical professionals to notice the non-physical illness wracking The Developer.
• And, finally, the ultimate destruction of The House represents a horrific mental breakdown, the effects of which our protagonist may never fully recover from... if anyone notices, if anyone helps him, and if he manages to survive his own self-destructive mental collapse.

Van Schoonbeek is Satan, or at the very least a Satanic Archetype.

The guy just gives off very satanic vibes. He shows up out of nowhere, offers what appears to be the family's (or at the very least, the parents') heart's desires in the form of the House, along with the fancy dinners, sewing machines and fireplace, he's constantly indulging in maniacal laughter, his behaviour is inhuman; appearing suddenly, changing his size, and at one point the House seems to turn into his head, and ultimately the parents are transformed into furniture, which very much feels like he's taken their souls as payment for the House being built, along with his workers demolishing their old house. On a lighter note, he also wears red, and Satan is often associated with the color red.
