Parents can be a bit restrictive when it comes to letting their children watch more mature films, but rebellious kids will always find a way. This entertainment involves terrifying horror classics, and films with sexually explicit material. Adolescents would never want to watch these movies with their parents. Obviously that never stopped most children from secretly viewing them, often with friends and siblings.
The reasons for watching these films vary from person to person. Peer pressure might mean that a child wanted to see something the rest of their friends had already watched, or they could have just been curious about something they had been specifically banned from viewing. Whatever the case, being told not to watch a movie guaranteed kids were going to go out of their way to check it out.
