I am a long time fnaf fan and I am not really a gore loving person and I have sympathy for everyone I know bur this movie is awesome for these reasons.
1 It is a good movie for anyone who is a fan but but can't tolerate a lot of horror. proof. I brought my mom who is not a fan to the movie and she was ok.
2 it has a lot of lore relevance with things like the silver eyes red eyes, the springlocks and the afton family.
3 for some context when I was starting out as a fan I would always watch the YouTube vid of fnaf characters interacting and being friendly ( yes I was that kid) and watching the one scenes where the animatronics are being friendly it was so wholesome and I enjoyed it so much.
