X-Men 3 (or X-Men: The Last Stand) concludes the first trilogy of mutants vs humans stories without director Bryan Singer while still trying to capture his beats. In this film, a "cure" for mutants is available, which divides loyalties and causes Magneto to again seek war against humankind. Cue appearances by Angel, Psylocke, Juggernaut, Shadowcat, Callisto, Multiple Man and others to jump in just in time for their 15 mins of fame and a big, noisy climax as Jean Grey embraces her dark side and becomes Phoenix! With the fate of the world hanging in the balance, can the heroes save the day? Not without some sacrifices and a few wasted characters, sadly. Some good elements, but not the best way to end the series...a bad turn which repeats itself again unfortunately in 2019's Dark Phoenix.

Chosen answer: 1) Apparently the combination of Logan's unbreakable skeleton and healing factor was enough to keep Jean from shredding him - it's possible to see his body getting damaged and repairing itself in a few shots. 2) Because, while he's capable of getting close to her mostly intact, the same isn't really true of anything he might be wearing or holding, so any cure syringe he carried with him would be destroyed. 3) Who knows? Given her extreme power level, the cure might or might not have worked, and, considering the final shot of the movie, which suggests that the cure isn't permanent anyway, her powers would likely return before long.
