Heh.. I didn't realize The Dead Zone was a movie. I read the book and have watched a couple episodes of the show with Anthony Michael Hall. Man.. I gotta find the movie. Walken is awesome.
Also, Hitler wasn't some half-demon spawn of Satan. He was just a guy. You're giving him more credit then he is due. He was no more evil than many other people before, and after him. He simply had a nation willing to listen to him.
