The worst book to movie adaptation, everything is opposite in the movie.
If you have read the book, I recommend you to NOT watch the movie.
First, let's talk about the characters, in the book Percy is a kind and nice guy but in the movie he is a selfish guy. In the scene in the museum, instead of focusing on what Mr Burner was saying, he was just listening to headphones. And this si just one of the mistakes in the movie.
