With the movie adaption of this children book classic, you get taken into this world and actually see the complexities of the wild things. They're not just wild, they have feelings and personalities that the book pages didn't get to explore. It was nice to see them come to life exactly as they look in the book, but the movie added names and characteristics that make them feel even more real then they did as we were kids.
Even little boy Max was more than just wild. The movie gave a back story to his family life and parent/child dynamic. You understood the wildness in him and his reasons for acting out. At times, you even felt sorry for him. Max Records (yes, the young actor is also named Max) portrayed Max as more than just a problem child and you couldn't help but loving him.
For an adaptation, I think this portrayal was well done.
