Writing

Michael Crichton is an obvious offender, but it's also true of a lot of "thriller" fiction, too. The author structures the novel in a way that seems clearly calculated to facilitate the adaptation to the big screen, because that's where the money is.

I'm not ready to throw out the "show don't tell" mantra, though, because it's possible to be rich and visual without being vapidly cinematic. As far as exposition goes, it only really bothers me when it takes the form of dialog or a conspicuous infodump that disrupts the flow of the story.
