He ends up doing night security at the mothballed family entertainment restaurant "Freddy Fazbear's Pizzeria" an 80s nightmare of arcade machines, ball pits and the piece de resistance giant dancing and singing animatronic anthropomorphic animals.
After some weird goings on he meets local beat cop Vanessa (Elizabeth Lail) who tells him more of the history of the place.
No good will come of this.
Video game adaptations are another cursed sub-genre and this comes from a niche survival horror indie game with a massive Gen Z cult following. Which makes it a bit of a poison chalice. Do it "wrong" and the fans will lose their shit. Do it "right" and most people are probably going to go "eh?".
Emma Tammi has probably steered a decent course between the two, which is borne out by a very healthy box office take and makes it another success for Blumhouse but I've got to say I fell into the latter camp.
The animatronic animals are of course creepy and haunted and do some murderising. There's a VERY improbable link between Mike and the goings on. Vanessa spends AGES not telling him everything she knows about the haunting to the point it's ridiculous and has weird conflicting actions/motives that simply don't ring true.
It's not very scary. The original game is apparently big on jump scares and this doesn't really try. It's also not very gory, which is something you'd expect from killer slashing haunted robots.
The whole custody battle thing seems pointless filler used to bookend the movie. I'm sure it's stuffed with fanservice but obviously I missed it all.
Overall not terrible but you've got to be a fan I think, 6/10.
