Huh? If you mean his parents' killer, as in the Burton movie, I really doubt anyone wanted that plot device retained. I thought that was a bad idea the first time. And it's a bad example, since that was never integrated into the comics canon, as was Peter's romance with Mary Jane. It's also a bad example because there was a 16-year gap between the first Batman & Begins, and an 8-year gap between the LAST installment & Begins. Much more significant than the gap we're looking at here, where the original cast COULD actually come back but Sony's deciding to reboot instead. The Peter Parker/Mary Jane romance-the core of all 3 movies-is still fresh in moviegoers' (and comic fans') minds, so I think completely disregarding it in favor of a character who died 30 years ago is a bad move.
