I'm not sure about unnerving. Psychologically, I know I'm looking at a recording. But when they're not looking at the viewer, it looks like they've got better things to do. I see this being used all the time recently, including on large productions. I assumed it's meant to convey the feeling of talking with someone who may also be talking to others. But it gives me hives (for which I'm losing points, but what can I say).
