This was my impression after first viewing the film. No less horrorific, to be sure. But IMO Berg was probably duped by his "captors". IMO too, despite earlier "reports", the acorn doesn't fall far from the tree. Just check out dear old Dad's "statements". It's all too convenient.
Where did you read that? aztlan.net? abovetopsecret? Don't be an idiot.
Let's get this straight: Nick Berg really was murdered on tape, without question. If you don't beleive me, watch it yourself frame by frame in Windows Moviemaker and tell me why his blood is pulsing out of his right carotid artery? (BTW, if you think that isn't enough blood for you, let me remind you that Kill Bill is a movie.)
Pass it on.
