The DCAU did a good job yes...Darkseid basically laughed when Supes punched him. Even in the end it took the intervention of Metron to stop the fight as Superman unleashed holy hell and Darkseid still got up and smiled.
I like the timeline that was posted earlier, but I guess I would like it better if Doomsday showed up at the end of Superman/Batman as a forshadow to Justice League where Superman dies. I have always just thought it made sense for the League to truly form because they all are needed to fill the void of a God amongst men.
