The Backrooms movie: A perspective from someone who isn't familiar with the lore

I went into this movie completely fresh—I haven’t seen the YouTube series, so I wasn’t looking for lore accuracy. I was honestly just curious because the story of a 20-year-old being given a major studio budget is a fascinating industry move.
After watching it, I’m left frustrated. To me, this felt like an amateur project that was given a professional-level budget without the necessary oversight to ensure the fundamentals of filmmaking were there.
It failed on a lot of levels for me:

Atmosphere: It’s marketed as an atmospheric horror, but I didn't find it scary at all. Instead of building dread, it just resulted in a headache from the erratic camera work.

Craftsmanship: The continuity is shaky (e.g., characters' physical injuries shifting based on the scene), the VFX for the wall-walking looked cheaply done, and the sound design felt like it was constantly forcing an emotional reaction that the script hadn't earned.

Storytelling: The dialogue felt unnatural, the actors struggled to make what they were given work, and the third act completely fell apart.

I don't think viral success online necessarily equates to the ability to direct a long-form feature. I feel like this was a case of someone being handed the keys to a feature film before they had the chance to hone the skills required to keep a story coherent.
I could go into a lot more detail on the specific technical mistakes, but it feels like a waste of time at this point. I think might possibly be potential here (but most people have at least some potential so that’s not special), but as it stands, it feels like a waste and grossly overhyped.
