Charlie and chocolate factory

I, saw Charlie and chocolate factory movie first.
Charlie is poor boy whose parents lost their jobs but also live with 4 grandparents. One day, he got a ticket which can have a change to visit Wonka's chocolate factory, which is the biggest one in the world. The child who get ticket and come in, can have a chance to be a successor of factory president, which Charlie had.
When I saw the movie, I was very amazed about chocolate factory's way to make chocolates. It was very amazing. But about Wonka, I think he is evil. Of course, children acted bad, but he treated them also badly. Also, I felt that he was even enjoying treating children.
