The trailer makes you think the movie will be EPIC, clearly that's not the reality of it.
This movie takes place after X-men: Apocalypse. In this film, the X-men have gone their separate ways, and mutants are no longer a threat to humanity. The remaining X-men that still live in the X-Mansion are now sent on missions by the government. In this film, there is the classic violence that you would expect in normal X-men movies; kicking, punching, hitting, throwing, blasting, e.t.c. In the movie, there are many flashbacks to Jean's past life, which helps the viewers get to understand more of her. A scene where a parent is killed by her own daughter; the daughter is shown accidentally flipping the car over using telekinesis when she is still discovering her powers; there is some blood shown, the dead parent's head is marked with a deep scratch. An alien race has the power to kill anybody by twisting that person's stomach. A man is shown in a hospital, a cast around his neck. A mutant is shown holding a knife, he eventually stabs multiple people with it. A girl electrocutes many people. A main character is thrown and stabbed in the stomach by a sharp wooden object. Some sexual references; a boy and a girl are shown living in the same room, it is obvious that they sleep together; they eventually kiss multiple times. Some teenagers are shown drinking at a party, some swear words.
