Bob Iger is a businessman. Based on the numbers, he makes the right choices. It's as if Universal fans were angry that the Orlando Resort didn't build new rides on Universal or original movies, but had to buy the rights for a WB franchise. Look, no offense here, I would also dream of new "Disney" attractions, however, I already think there are too many, all new projects are based on Disney/Pixar... I'm much more excited by original storylines, such as BTM, Soarin, Everest, Spaceship Earth etc.
