There's a lot of debate within the scientific community over whether it actually takes 25 years for a person's brain to develop. Pedophilia has nothing to do with movies about a teenager and an adult falling love with each other. Yes, it's true that the American culture tends to stigmatize these scenarios more aggressively than other cultures do. However, if you're viewing the movie Gardens of the Night, then you're watching a movie about dangerous pedophiles inasmuch as the victm in that movie is an 8-year-old girl. If you're watching American Beauty or Diary of a Teenage Girl, then you're merely seeing a film about a forbidden romance between a teenage girl and an older suitor. It doesn't necessarily have to be about anything predatory.
