This petition is ludicrous. Most of the people who sign it are fans who are disappointed because they had false expectations. They were expecting Rey to be the daughter of a famous character, they expected Kylo Ren to go back to the "good" side, they expected Rey to turn to the Dark Side, and they were expecting Luke to be a human Yoda...

If the movie was done like the fans expected, it would contain no surprise, no novelty, and everybody would be bashing Johnson for that...
