Simply marvellous, it's really a book that you appreciate more every time you read it.
Though I felt that the filmmakers did a couple of things that was better than the book, though the product was inferior. For one, the first half of the awesome V speech, before it dragged to the point where you could tell they had to look hard through a dictionary to find the appropriate words. The ending explosion in the book I also felt should've been given more than one small panel, so I liked the bigger exposure in the film.
