Could have been amazing. Fun? Yes. Would I see it again, No. This is one of those movies where plot comes out of nowhere and left me thinking 'what!?'. I can see the potential, and I have always loved FNAF, but i wish they leant into the camp sort of humour that lies behind the absurdity of what's happening on screen. I think it almost takes itself too seriously. There were moments where I laughed, or cringed, but I don't think that was ever the intention when that particular scene was made. Had they taken a similar approach to the film that M3gan did, where she literally just dances and sings and its a completely bonkers movie, FNAF would have been incredible. That being said, I think this movie also needs a UNRATED cut. The film was marketed almost like a gory slasher, but upon watching, all of that felt removed.
I really do hope they get a sequel, because I'm interested to see where the story goes and how they do it- hopefully learning from the mistakes of the first one. It was a pretty bad movie, but it could have been amazing.
