Well, for me, the shocker was the public reaction to it. That people thought it was hilarious and goaded the Prime Minister into doing it, making it into a viral sensation. It was only as the act began that they realised the horror of the situation.
More to the point, someone could have found the victim within that hour and stopped the whole thing, but no-one did because they were too preoccupied watching it on TV.
Exactly. The "oooooh" moment isn't when we find out about the early release. It's when we realize that the people the camera is showing you during the, ah, main event aren't the ones watching the most disgusting and degrading thing happening at that moment—that pleasure's been reserved for us.
Then there's the framing and lighting on that last shot, which made me sit up straight and go, "oh, crap, I need to start paying closer attention to the film-nerd details in this show!"
