It would be very difficult to have a very popular show of any type, but particularly those that had some sort of military theme without Good and Evil.

Nobody wants to watch a show where it's hard to figure out who to root for. I can understand some of the intense drama that can be played out when good and evil is not so black and white but multiple shades of gray..However, in most cases, a show would not last long with out definate white hats and black hats.
