Lord of the Rings trilogy (books were a chore with all the unneeded camping and such)
Blade Runner
The Shining
These are the ones I am immediately thinking of. Will try to come up with more.
This is a complete non-point, as obviously for a movie adaptation to be made, there has to be a book to adapt it

As for LOTR being a "CGI-fest", actually that fits The Hobbit trilogy better. In LOTR Jackson was pretty adamant on heavy use of actual elaborate sets and practical effects a lot of the time.
Obviously there is significant amounts of CGI (which given the material is kind of inevitable), but calling it a "CGI-fest" like you're trying to compare it to Transformers or something is just an uneducated comment.
LOTR isn't CGI fest by any stretch of imagination. They're brilliant adaptations (theatrical versions). But I don't think they're superior to the books.
Okay dudes, lots of book vs film debates are good, but IMHO none are as intense as LOTR books v films.
Time for me to weigh in, those films have a special place in my heart because they were made down here, near my home and because I was an extra in the Hobbit ( and I can't resist the chance to drop that in whenever I can).
As for CGI what IMO makes LOTR films superior to the Hobbit was the use of practical locations - yes folks parts of NZ are that beautiful. The Hobbit used a ton if CGI locations, trust me I worked on one of them.
Now as for books v film, with the Hobbit I prefer the book - I have fond memories of having it read to me by a teacher when I was 7, and when I used to be a school-teacher I read it to at least 10 different classes. The films were too drawn out. Yes, a lot happens but there was no need for 3 x 3 hour films - and the over use of CGI diminishes my enjoyment.
LOTR is a bit different. First, while Tolkien's ideas were amazing ( although reworking of classic myths) his narrative style has some weaknesses. Don't get me wrong I love the books, but I find his use of flashbacks a bit heavy handed and there are a lot of characters who are mere plot devices ( e.g. Erkenbrand, Glorfindel).
However I put that down to Tolkien being an academic rather than a novelist and also that he was writing at a very different time - before TV was widely available, so people were used to slow narratives in books. Some parts of LOTR are beautifully written with wonderful language, and I would suggest that Tom Bombadil was a bit unnecessary but otherwise the narrative is solid - no disrespect to Peter Jackson but the second book has a much stronger ending than the second film. Like any great books they take an effort to read, but they're worth it.
Having said all that I love the LOTR films and the books equally and I can't honestly say which are better.
