Amazing Spider-Man: Renew Your Vows #1
This issue is such a treat. I really love Dan Slott writting Spider-Man but he hasn't done as good of a job encorporating Spider-Man classic supporting characters. His recent series showed very little of MJ and not a lot of appearances of classic villains outside of the Green Goblin. This is a great "what if" story that really feels like classic Spidey.
