It's a shame that Roger had to go in this fashion. But, I look at it this way... if there is a radical shift in the show, I can just simply ignore what it might become and remember the show for what it was. No emotional baggage attached.
Getting fired is the nature of the biz, folks. It happens in any corporate structure. You don't perform or you slip against competition, someone gets the heave-ho. You feel bad for the man who lost his job. I'm not saying I support Fremantle (actually, I don't, but that's another can of worms.)
