dir: Simon Kinberg
Almost everyone that liked the first two X-Men films really hated the 3rd one directed by one of the worst directors in the business, being the appalling Brett Ratner who I hope never gets to direct again. That 3rd flick, The Last Stand, was pretty hateable. In it the character of Jean Grey goes fucking crazy and wants to destroy the world, for some reason.
Bryan Singer, who directed the first two flicks, did not get to direct the third one, and was so offended by it that when he got the chance in X-Men: Days of Future Past, he made it so the earlier film never existed. Would that we all had such power to undo the actions of the past. If Bryan Singer actually possessed such power, perhaps he could travel back in time and undo the sexual assault and harassment he’s been accused of. I hope neither he, nor Ratner, ever work again, because both of them are pieces of shit and neither deserves forgiveness.
So, one of the people who wrote the third film, being Simon Kinberg, decided it was shit too, and thought “maybe I can do the same story properly, and people will like it, and like me too, maybe?” So he decided to direct a version of the Dark Phoenix storyline where Jean Grey gets even more powerful and threatens to – something – the world. I dunno, she kills a few people unintentionally, and probably had some impact on property values.
