This clue makes me want a Boogieman original!
Edit: Adding some guesses to Legacy’s clue, assuming it’s regarding a father being part of a horror movie’s central plot...
First I want to say Twin Peaks, but Legacy already mentioned he’d be shocked to ever see that IP. There’s also Rosemary’s Baby (the devil is the father), The Hills Have Eyes (the father is the leader of the clan), and Amityville Horror (the father is possessed to kill his family).
