Watching this, I'm left wondering why my brain doesn't want to blend the visual and the audio. I don't think it's the bad lip sync. I have this weird feeling that these persons, were they real, wouldn't have these voices. But I can't quite put my finger as to why. I haven't watched movies dubs in a while, but maybe that's the same kind of phenomenon that makes dubs sound bad. Or maybe we grow an intuitive sense of what a person's voice might sound like based on the appearance of their face's bone structure and muscles?
