Not sure I totally agree here.
I think Sony is hamstrung, because they could not do a long term tale as Disney/Marvel can.
When they first launched Ironman, no one was sure what would be next, and how it would grow, but yet Disney and Marvel did, as they had Easter eggs in the credits. We now know, they had a long term plan, and that plan involved Hero's we have not seen in Movies in the past. Plus long term plans to move to new series with Avengers as the climax.
Sony doesn't have that capability. They have X-men and Spiderman, and thats it. While Spiderman and Wolverine have interacted in the comics, X-men and spidey haven't. There is no long term direction to go.
Add to that, Sony basically admitted they blew it and completely retold the same stories in both series. Hitting fairly well with Xmen, not so much with Spidey. That to me is their biggest issue. They see superheros are hot, but only have limited availablity, so they are struggling to keep revamping what they have.
I wonder what happens with the Fantastic four remake as well, as I see this failing as the Spidey revamp did as well.
