Just got through watching Superman:Unbound (an adaptation of Superman: Brainiac), and I was staggered at how it completely mirrored MOS in a number of scenes! Seriously, you gotta watch it and see. Simply replace Braniac with Zod and you have a blueprint for MOS. I'm not going to tell you what or where the key references/scenes are but you WILL see them and make the same comparison. I can't help wondering if Goyer had meant to draw so completely from this, or vice versa.
