"Cohen appears to strive for accuracy in the same way as Michael Moore and Morgan Spurlock."
He doesn't 'strive for accuracy' in anyway at all or claim to. Did you think it was a documentary?!
I realize that the persons' behavior with Cohen are open to interpretation. But what is most often related in reviews of this latest film: It is a window into the persons' real personalities. Their prejudices, flaws, etc.
I can't help but think that this may be something of a backdoor documentary.
