They included everything about FNAF 1. I just feel bad about Cassidy. I feel like it isn’t the same without Charlie and Cassidy in there. I love the actors and the movie plot, But a couple things about the lore, Micheal should have stayed as William Afton’s son. they also should have kept the original lore. Otherwise, it was a genuinely suspenseful movie and I would 100 percent watch it again. It’s more fun with friends and you may need a bit of background information to fully understand the movie. It obviously isn’t gonna be going in depth into all of the FNAF games and books, but the ball pit and hiding in there is a clear reference to In the pit. I truly believe this is a great way to finish off the series. It isn’t extremely gory, but it’s not sunshine and rainbows either. Also, I appreciate the thought put into the thought processes and personalities of the characters. Micheal truly seemed to be struggling, and the dreams had a dream-like, vivid effect with them. This is one of my favorite movies by far, and I’m considering watching it again with a group of friends.
