Instead, Aurora should have been the protagonist ... and in fact, it's incredibly weird that she's not. From her perspective, she wakes up 90 years early with some guy she's never met before. Sure, the guy she's with is Chris Pratt, and that sounds delightful, but the scene in which she meets Pratt for the first time would take on a far more sinister tone if the audience only know what she knows.
Now the whole thing is unfolding as a mystery. Can we trust this guy? Is he telling the truth? Now you've set up the audience for a gut punch of a revelation halfway through the film: He alone woke up by accident, and rather than ride it out, he essentially abducted her. He ripped her out of the life she was set to live to instead spend the rest of her years trapped on a spaceship, with him and only him.
