That was well said, whether you get berated for it or not.Ideally, if the stories in the series are well told, and in this case also well illustrated, then it would a series worth reading about. That being said, it really does depend on who the titular character is. And in this case, the reason why people read Spider-Man and why he's been so popular for so many years is because they like and can identify with Peter Parker. This was a undeniable fact that the folks at Marvel found out the hard way when they made Ben Reilly "the real Spider-Man"; they have been successful in having him "reclaim his identity" as Spidey, but the way they told the story made virtually impossible for Ben to "reclaim his identity" as Peter Parker, which was far more essential.
Granted, we've had Spider-Man comics in which Peter Parker was not Spidey, such Miquel O'Hara in Spider-Man 2099 and Miles Morales in the current run of Ultimate Comics Spider-Man which are, more or less, successful. But the thing is, readers understand that these Spider-Men take place in alternate universe rather than in mainstream continuity. They still understand that Spider-Man is not the costume but the person who wears it. If the new Superior Spider-Man isn't Peter Parker, the character devoted fans have been encouraged to follow for decades, then his replacement better be a person fans would want to enjoy reading about and following month after month, someone they can identify with, and someone they wouldn't mind filling in so long as the real Spidey comes back. And if not, Marvel shouldn't be the least bit surprised if the fanbase start dropping the title like flies.
