I will buy this, for the most obvious reason: It will be awesome, and interesting, to see the interaction between an adult Peter Parker and a young Miles Morales, written by a guy who has clearly written enough stories featuring Peter Parker at both ages to make it really good.
Make no mistake: Like any writer/fan dynamic, there are things I wish Bendis would do differently. But there are clearly things he does well, and this concept suits those strengths perfectly.
