Jesus that's twice now they fucked up the Phoenix story. With as much as this film was delayed it's really no surprise it came out a mess. Was also kinbergs directorial debut. He was a producer on basically all of singers xmen films. At least the newer ones for sure.
I'l say this though: Having her kill Professor X in Last Stand was kinda dope. Granted, they undid it some kind of way for the flash-forward scenes in DOFP and Logan, but it wasn't something I would have expected.
