Superman and Batman reboots?
From Marvel I've read The Amazing Spider-Man vol.1-2, and full Ultimate Saga including the New Ultimates, so bare with me.
And, to the question.
I recently gotten interested in Superman and Batman comics, but I want to know if there are any reboots of the series, such like Marvel's Ultimates?
If not, which issue of the series would be the best for me start from, if not from the very beginning, that includes both heroes origins?
