I was a little too old to be a 'fnaf kid' but still knew the series well enough. I know the lore and theories etc, and thought this was really cool! Cool shots and camera work too. A bit much for younger kids btw, kid and dad beside me left like half through the movie because he got scared. Not super gory but there is a shot quite unexpected where a mutilated body part it shown quickly.
A fun movie, quite enjoyed it!
