I've been waiting 7 years for this movie to come out, and I was not disappointed. (INCLUDES SLIGHT SPOILERS)
First of all, the little easter eggs and references sprinkled around the film were a nice touch to those of us who are committed FNaF fans.
Second, the animatronic designs were AWESOME, I hope the people who did this were paid double.
Third, ARGH THE CAMEOS WERE GREAT. Unfortunately, I got the MatPat one spoiled for me.
Fourth, the music chosen for the intro and credits was the right choice. I honestly didn't expect TLT to start playing, and when it did, that was the most exciting part of the movie for me. And the intro song was an instant banger.
However, I don't go without my own criticisms. I thought that the springlock scene was underwhelming and anticlimactic. When compared to the game and book scenes, this one is...below expectations. I feel like they could've gone all out, even with the PG-13 rating.
But this was still a great movie and I hope that the other 2 can build and improve on it.
