Being a video game movie, I'd say it was a pretty solid and well written film. It ain't perfect, but for what it is I think it deserves a five star review.
It was packed with fan service, plenty of funny and tense moments throughout. I went to the theaters to see it and not just the kids and hard-core fans liked it, but parents did as well.
It's a horror movie that managed to entertain both children and adults. That's kind of hard to pull off and this film managed to do it.
It won't change the film industry, at least not majorly. But this is definitely some great fan service for anyone who likes FNAF.
I reccomend this film and I would definitely see a sequel to this.
