For me it’s NO CONTEST: John Powell’s theme in X-Men III: The Last Stand for Jean Grey/Dark Phoenix. Holy shit!!! Particular favorite moment of that theme in the score is 2:28 into this cue: https://youtu.be/drPGnQLVIK4 ... Yavar
Great minds think alike. The Dark Phoenix motif/theme from X-Men 3 immediately came to my mind when I saw the thread title.
