Watched this earlier this evening. Very cleverly made; almost David Lynch-like in how it leaves itself open for so much interpretation, just without being surreal like Lynch usually is (very much the opposite; its clinically real for the most part).
It's difficult to discuss without giving too much away, but I like the potential allegory to certain aspects of French (or any old colonial power's) history that have been conveniently forgotten, and the possible identity of those who are forcing it to be remembered.
That said, I'm really not convinced that the childhood actions that it all centers around were so bad, given how young (five?) he was. Not that that excuses his inability to face up to it in any constructive or unselfish way in adulthood; he really is a first class prick.
(On the other hand, Haneke is clearly having fun winding up the audience, just like the guy at the dinner party with his shaggy dog story. And yet still the girl asks if it's true!)
