I'm a massive Morris fan (so much so that I've read about this contraption before), and while I've only watched a few minutes of the documentary you linked, I do think that the interview style is different. It's not just about talking to the camera, but rather about talking to the camera as if it's human - McNamara, for instance, regularly wiggles his finger at the camera, as if he's lecturing to you in your seat. Toss in the fact that Morris regularly shouts his questions or comments from somewhere off to the side - probably somewhere across the same room, as dictated by the way that this system works - and there really is an unsettling way that it feels as if you are the focus of what is happening, with the SecDef during the start of the Vietnam war and your crazy shouty uncle over for dinner. It's just so hard to articulate how it feels, and I'm sure the effect doesn't work on everyone as well as it does on me. Errol's movies have changed my opinions on both McNamara and Rumsfeld, though, and that's a phenomenally tall order (and, I think, speaks to how vividly human he can make his interview subjects).
