I don't wanna contest your take just for the hell of it but this feels really incongruent with what I watched. Whether the movie is great or mid is less of a concern to me than the video game comment. The movie felt very traditional to me, translating a very loose 'creepy-pasta' idea into a traditional horror movie format.
To that extent I personally thought the movie did great, but I guess I'm highlighting my disagreement because I don't think there's any video game influence on this movie. I know there are a lot of games themed after the backrooms but the concept itself is agnostic to video games, it's a communal/shared universe like SCP that spawned from a particularly fire paragraph-horror story.
You might appreciate it a bit more if you see it as less of a 'video game' movie and imagined it more as one person's big-budgeted interpretation of a cultural horror idea. Sorry if I've read the wrong implication from your post and you already knew all this stuff.


I'm anything but a backrooms fan but I particularly enjoyed this movie. I think it's best appreciated coming from the perspective that the backrooms is one of those ownerless shared fiction universes that almost never get adaptions with any sort of budget behind it for obvious reasons, much less when they have very niche or novel premises like 'noclipping out of reality to end up in procgen horror hallways'
I was keen to watch it because it made me fantasize that we might get some decent money behind an SCP project one day, they feel like very similar universes in how they have evolved.
