I am still a little torn about the film. I understand that it's Scorcese and everything, but the book is unique.
I hate people who think that film adaptations of their favorite books will ruin everything, but The Invention of Hugo Cabret is a book that is sort of ground breaking as far as children's literature is concerned simply because it's kind of a combination of a traditional book, with large portions of the book consisting solely of pictures that must be "read" in order for one to receive the full context.
While I can't say that people here should or shouldn't go see the movie because
a) I haven't seen it yet and
b) that's Bob's job,
I can say that if everyone here reads the book, they'll be shocked. Even as a teacher, I don't really keep track of the current trends in children's literature, but this book is one-of-a-kind and has an amazing depth of character and story for a kids book. There isn't anything else like it, and probably won't be for a while.
