Johnson didn't kill Star Wars, fans did. They drove Lucas away with their vitriol. Then they spewed more hate at the new works until JJ decided to just give fanbois what they wanted rather than a good movie. People who put their hands over their ears and screamed "nuh uh, Luke wouldn't do that!" killed Star Wars.
So it's all the fan's fault that people didn't care for a blockbuster movie that ultimately was just a rehash of existing plot mechanisms with almost no originality?
Instead of blaming fans for imaginary hate... maybe you and Iger should step back and start to accept people JUST DIDN'T LIKE YOUR PRODUCT
