Superman vs Doomsday is the greatest Superman story ever told. Superman vs Batman is the second greatest Superman story. Are telling me that Zack Snyder will use up both of the most important stories of Superman's legacy rolled up into one movie? NO NO NO. That is the dumbest thing ever. There is no way Zack will make Superman vs Doomsday a throw away story like that. It is a story of its own and DC will milk it for all its worth...(a couple of billion dollars) Two things wrong with this idea. First, Doomsday is too strong of a character and will compete with the "new" Batman introduction. This will also take away from the Batman vs Superman topic. Second, is the money. DC is not going to throw all the eggs into one basket. They save it for another movie and make more money off Superman!
