meh, I don't think anyone gets fired.
Disney controls a lot of the market currently, Sony can still produce good super hero movies. Contrary to what most believe, I thought the Amazing Spiderman movies were pretty good. The things I didn't like was the villain designs for Green Goblin and the Rhino. Other than that, the movie was done really well in my opinion.
Disney wanted 50% of ticket sales and they control more than that (if I am not mistaken) on merchandising sales. So essentially Disney would end up making more money on Spiderman than would Sony who owns the rights to the character.
If Sony doesn't like the deal that Disney proposed they do not have to agree with it just to appease fans.
