Honestly I think its a matter of personal taste. So Langsta is 100% right for him, As he most likely doesn't like any films more than the book. Which is understandable. I myself have some I prefer some over the books. Like Watchmen, V for Vendetta, Gone with the Wind, The Wizard of Oz, Alice in Wonderland (disney cartoon), The Jungle Book (disney version) and more.
I think Planet-man summed it up well with "sometimes one has basic ideas and the other does something really original with them." A lot of the once I prefer are very different to the book (Ironic since thats one thing I hate about LOTR. Some times they can remove the silly parts other time they can add a new cool scene ect... So I think its possible to say "The film is better" but I think it's ok to say "the book is better" as its just your taste.
