Man, I love Kurt Busiek.

Reading Amazing Fantasy #16.
It's always nice seeing early early Spider-Man. Early Spider-Man never intended to be a superhero. That much is constant, but it's interesting to see his just how he fell into the role.

Also reading Spider-Man: Legacy of Evil.
It's kinda funny to see people in-universe assess events that readers have firsthand knowledge in. This is probably the moment where Ben Urich really figures out who Spider-Man is.

And finally Spider-Man: With Great Power...
Out of all of the AUs, this is the one that I want a continuation in the most, and the reason why will become obvious when you finish the miniseries.
