This is like a quilt you buy at a Goodwill store. It's got a few pieces of material you recognize but mostly it just smells. It fails to be an apocalyptic tale because, is it an apocalypse? It fails to be revenge of the dead bestie tale because, is she?
It fails as a "we gotta get out of this room" tale because, do they? And it fails as a demon inside tale because, is it? I believe four people, loving four types of horror, were going crazy during 2020's lockdown...smoked some bad PCP...and decided to staple their "epic vision" together with toilet paper & hand sanitizer and came up with this flick. Then they went back to trying to AirFry a leather sandle.
