Don't make Tony Stark the creator of Ultron!! He was never important in the creation of Ultron and it was Hank Pym (Ant-Man) who created him. Stop trying to shove Iron Man down our throats and make him do everything. Stick very closely to source material. When you tried to do something different the fans didn't like it (Mandarin Twist). Joss I know you think that you don't need Pym to have Ultron but in all honesty we do. Tweet @Marvel and @josswhedon to give what the fans want. Ant-Man creating Ultron!!!
