Thoughts on the fnaf movie(Spoilers)

The movie was good but the story was so confusing, I don't get why they would switch the families around but I think it kinda makes sense sorta???? My theory is that Henry and Afton sorta switched,so that Afton is the one with the robots of his daughter,that would explain alter ego Vanessa "Vanny" but idk then the other family doesn't make sense and it was never clear how everything fit for me 😿
