Re: Changing the roster for Avengers 2?
It seems to me that Marvel Studios have very little to gain from making a deal with Sony to include Spider-Man in an Avengers film. The audience that would see anything with Spider-Man but won't see an Avengers film is almost certainly far too small to be financially significant, especially given the obvious mass appeal of the Avengers as they are, therefore, all Marvel Studios are doing is forking large amounts of Avengers money to Sony while taking less for themselves. All that for the benefit of using a character that hasn't contributed to building the MCU and hasn't been guided by Whedon's creative vision as the MCU will have by Avengers 2.
So, Sony benefit by getting lots of money for putting in no work and Marvel Studios benefit by getting less money and undermining the entirety of the shared universe they built. Yay?
