It’s a film (I’m not sure if it’s Animated or live action) about a daughter and a father that move into a new town, they go to a bar or something where they meet hunters (for demons I think). Later in the movie while in an amusement park her dad is forced into some kind of slavery and he remembers that his daughter is in a danger, so he turns into a demon with horns growing out. The film has an happy ending and it’s a family movie. Nothing too scary I watched this as a kid.
