Michael Haneke is a very, very bad man.  He punishes his audience, showing them the things they want to see and then making them feel like assholes for wanting to see them.  "Funny Games," which he's made twice now, is perhaps the ultimate middle-finger to an audience, a film that promises you terrible things, then asks you why you would ever want to see them.  Remaking the film almost shot by shot is the sort of perverse idea that appeals to a sadist like Haneke, and there is something even worse about watching these terrible things happen to Naomi Watts because we already have an attachment to her from previous roles.  The moment that sent shock waves through the theater, though, involving a rewind of a key moment, is such a reality-bending idea that Haneke must have gotten the giggles both times he did it to an audience, an almost complete violation of the trust we place in filmmakers.  That's the point, and he made it with the biggest sledgehammer he could find.
