I've come to really appreciate the Rhino over the past decade or so; he's been in some stories that really provided emotional depth to the character, who I previously saw as just a flat strong man.
Y'know how, for a minute while he was Spidey, Ben had that weird relationship with Jimmy 6? I'd actually like to see something similar for Peter and the Rhino. I think an ongoing storyline about the growth of Rhino as a hero through his relationship with Spidey could become a classic.
