I can understand why Nolan an Goyer avoided Joker in the Batman Begins; Joker had been done to death in the past, and they instead focused on something new with Scarecrow and Ra's al Ghul.
If this Zod crap pans out, then Nolan and Goyer are only serving to make "Richard Donner Continues Part II". There is absolutely no reason to save Brainiac for later, and it's ridiculous that he hasn't been used in *any* film up until now.
I hope the Zod report is wrong. I don't want to see Zod. At all.
