Violence is commonly used in films, television shows, and video games to drive storylines and create conflict. However, media violence often depicts unrealistic consequences like characters recovering quickly from injuries without long term effects. Additionally, characters are typically reduced to simplistic "good" or "bad" roles without depth or humanity. Studies have found that excessive exposure to media violence can increase aggression in children by reducing empathy and making them less cooperative in solving problems. However, parents also play a role and should teach their children to think critically about media messages.
