This film tries to do a lot of things, but fails at them.
* The acting is....bad. Not as terrible as the "Bad Ben" movies, but bad. The drunken uncle is next level awful though. The lead, the Youtuber, is grating. She gets better, but man. It's a slog through that first act.
* This isn't a horror movie. This is a jump scare movie. There's no real tension built up because you don't care about anyone, and the killer has no rules they have to follow because SATAN. It doesn't help any that the killer has a total dad bod, and you can see it for all of its glory because they didn't get a robe and hood that fit.
* They try to have a "message" about tolerance, but it's all so very surface level. There are only two black men present in the entirety of the film. The girl's boyfriend, who is related to the people who assaulted her? Or maybe they're talking about someone else? The writing is so poor that it's not clear. And the step-dad in the end, who is beyond stupid. For a movie that presumes to be about racial tensions and "We're really not all that different," we seem to only hear from white teenage girls. It comes across as valley girl "racism sucks" nonsense with no actual knowledge of the horrors of racism, even though they apparently live in a town that is steeped in racial violence. You *can* blame it on the acting, but the writing is to blame here to. You just never believe any of the girls.
* The writing is nonsensical. So the lead realizes she has to runaway in the third act, but she pauses to put on her socks and coat *very slowly*. The summoned killer is apparently a KKK member, but no KKK member has ever looked like that? Did they want their KKK-cake, but didn't want to actually buy a KKK hood? The uncle dies, but he's the one who did the devil summoning? Why would his summoned killer kill him? And the jumping between found footage is nonsensical. Why do we go to the final daughter and step-dad? Literally why? It does exactly zero for the plot.
It's kind of funny bad in places where other Amazon Prime movies are just plain bad. But that's not enough to recommend it.
