My three year old loves this book, so we decided to try taking her to the movie. She has never been in a theater, so it was her first time. She loved watching the trailers on the website. She did very well through most of the movie, but lost all interest by the end. I don't think she had any idea of what was going on.
As an adult, I thought the movie had beautiful cinematography. It was very artistic, and true to the way that children interact with each other--trying to figure out all the ins and outs of social politics.
