The Prestige and Jaws are my immediate thoughts on this one. The Prestige is a weakly written mess with a stupid modern day framing device which adds nothing but a seriously shoddy ending twist and the film is far superior. Jaws isn't actually a bad book truth be told but fairly unremarkable. The film however was amazing.
I don't agree with the several people saying The Shining was better than the book though. The film has some good moments and yes it's all very clever from a technical film making point of view but as a story with characters it's very shallow and my least favourite of Kubrick's work (that I've seen so far). Contrast that with King's book where characters are the be all and end of his novels and the film seems like its innards have been scooped out.
