From that standpoint, I think the movie has to be superior to the book, considering I was actually able to watch the movie.
24 Years and Counting...
That said I really enjoy his books.
For many it depends on whether you read the book first, or saw the movie first. Kind of hard to say a movie was better than the book if you didn't read the book first. A book is all about anticipation, where movies are often just a lot of glitz, music and star power.
When I see a movie come out that interest me that is based off a book I try and read the novel first. When I saw that the movie "Shooter" was coming out based upon the book Point of Impact I read the book first. I loved the book and enjoyed the movie. Both have their pluses and minuses. The book was much more indepth and had some better moments while the movie did a very good job of adapting it to the big screen.
A River Runs Through It. Its a great book, but the visual aspect of the movie maybe makes me say that the movie was better. Its tough though, as they are both good.
