""The other," was a good story in my opinion. not a perfect story, but a good story, whose ramifications SHOULD have been explored further."
Actually, Jim Butcher did a tie-in novel "The Darkest Hours" recently which fulfills your request. It's never going to be Pulitzer material, but it's fairly enjoyable.
If nothing else, it's worth reading because:
1. Peter actually gets to be heroic.
2. It fleshes out the Rhino's characterization nicely.
3. It's entertaining -- Butcher on Spidey is a godsend if you like snarky dialogue.
