I watched it with my friend and I absolutely loved it! While it might not be completely lore accurate to the games, I feel that if it was there wouldn’t be anything new to watch and it would’ve been boring. So I feel that switching some things around makes the most sense. Mike not knowing anything about Fredbear Diner makes it so the viewer can learn stuff a long with him as we go, which is very important for understanding what’s going on. But even with all that I really loved the cinematography and visuals the most, the colors of the diner were really pretty with the contrast of the setting (tbh the whole movie was just beautiful). And the animatronics were so well made and felt like they were right out of the game!
Overall I feel like you don’t have to be a big FNAF fan, or a fan at all, to like movie for what it is! I know I’ll definitely be rewatching it a few times!
