Yes it is true. Did he in the Gendy cartoon?
Thanks for the link to the review. The Australian media hasn't been kind either. I don't have links though, I'm talking about print press.
Also your sarcasm detector is a bit off ;) When it comes to critical review Lucas always seems to fall back on the fans expectations are too high. Whether it be the prequels or that 4th Indiana Jones movie that does not exist.
edit: it seems Oz did not. I would have surprised me if he had.
