They have the final word on what they make. Hes an employee, not a producer. I think they wanted to work with Wright but when he showed them how he was ultimately going to make the movie, it all went bad. Just because he made some fun quirky comedies with Simon and Nick doesnt mean it would be right for Ant Man. This was going to be a huge franchise movie, not one of his trademark pub comedies. Lets not forget, Marvel saw/knew what he was going to do for years (whereas we havent), hence the troubles.
I dont care what Badass Digest thinks or any other site. Its not up to them or Edgar Wrights fans. Hopefully this will be a learning experience for all involved. Marvel will make better decisions on who they hire and Wright will only make the kinds of films he knows he has control over from inception to post production.
