Hate to follow the crowd, but I have to agree. You can live for hours in the book, but you can only watch the movie. You can meet and feel the characters better in the book and empathize more because you get to know them better. You can see in your mind's eye the places and the people and smile or cry with them. Reading a book is a totally different experience than watching any 90 minute movie.
Don't get me too wrong, movies can be fun, exciting, romantic, and even thought-provoking, but a good book can touch the heart and mind more deeply and intensely. I have learned more from one book than I have ever learned from watching the movies.
