Entertaiment is about making people laugh and feel good. It is also about creating social bonding and building stronger families, a thing that is becoming less and less common in todays fast-paced world of chasing a promotion at work or earning more money. It is about enjoying life, as you never know when it will be too late. Entertainment can stimulate the brain to realease seratonin, dopamine and other chemicals, wich is a great feeling considering the way the human mind was evolved to understand the world.
What seems entertaining to one person may appear cruel or demeaning to another. The familiar forms of entertainment have a great capacity for creative remix, which has helped ensure the longevity of many themes and images.
