Hey, look! It's based on a book, it's about 9/11, and it stars Tom Hanks and Sandra Bullock! Must be Oscar time again:
The problem with adaptations of books narrated by children is this: When you're reading a book, you can forgive a precocious narrator because you're effectively telling the story to yourself. We all secretly believe we were precocious children. But we hate other people's precocious children, so when you make a movie about precocious children, you have to convince the audience not to hate the child first. That can be an insurmountable goal.
