In his other (and presumably final) series for Travel Channel, The Layover, the production team has switched up the rhythms a little, and it seems he has followed suit in his voiceover. I'm not sure it's conscious, though, because the direction he has started to follow is even more off-putting. Bourdain has started to sound ... almost ... Shatneresque ... in his ... pauses.
Bourdain's appeal supposedly lies in his seeming naturalness in front of the camera: the audience gets the sense that he is being himself. You'd think by now, a decade or so into his TV career, he would have figured out how to sound that way, too. Yet he still comes off as self-conscious and ill at ease when he speaks, even when he isn't narrating. It just goes to show, I guess, that narration isn't as easy as it sounds.
Or perhaps he is a lot more camera-conscious, in speech and appearance, than we think.
