Could I suggest that the hypocrisy is caused by the fact that since Tolkien created ME, he is able to make the impossible possible, but since PJ is only the director of a movie based of LotR, he is considered by the "True Believers" to have no right in doing such things? Its Tolkiens world. Aragorn, Gimli, and Legolas can, in his world run that far in that amount of time. Denethor on fire..... well, he didn't.
I don't want to join in on this arguement, but I did want to make an excuse for the hypocrisy(and sure, I'm often a hypocrite...

).
