Why is Dieter Bohn so Negative about the Nexus 5?

Anyone else noticing the negative reaction to his hands-on video, especially on Youtube? I'll admit he seems kind of cynical and not interested, and was pretty shocked at how dismissive he was about the camera, having not even used it yet. But I'll just wait till a review comes, or at least when someone else does a first impression (preferably MKBHD).
