X-Men: Dark Phoenix - 8 Mistakes It Must Avoid
3. Fail To Tell The Phoenix Force's Origin Story
This was another of The Last Stand's cardinal sins.
The Phoenix Force is one of the most awesome powers in the Marvel Universe, with enough ka-pow to shatter worlds and reduce civilisations to dust.
It has an entire mythology behind it which is ripe for fleshing out on screen, but The Last Stand took the reductionist approach and repackaged it as the repressed part of Jean Grey's psyche, bursting to the surface.
Dark Phoenix cannot afford to make this mistake. It must delve into the origin of the Phoenix to set the stakes, establishing it as the most dangerous entity in the universe.
Sticking closer to the comic book source material will help Simon Kinberg swerve this particualr pitfall.
