Part 2: Moving Forward
Toward the end of the film, Luke is leaving the mortal world, and the frame is mostly filled with the twin suns of Ahch-To, burning in the sky. One is slowly setting, and the other is just cresting the horizon. Metaphorically, the film is closing the book on one era of Star Wars and starting up another.
Last Jedi takes the time to deconstruct and interrogate various aspects of Star Wars and show new sides of those aspects. It admits that the Rebels weren't perfect and that you don't need to have legendary parentage to be a hero. Yes, Force Awakens was the beginning of this new era. But that film, as much as I adore it, was trying to recapture exactly what Star Wars was. This film is designed to elevate it to new heights.
At one point in the movie, I found myself trying to figure out who among Finn, Rey, and Poe, was the "Luke", who was the "Leia", and who was the "Han". Then I realized that was stupid. They’re all their own characters. They have their own personalities, traits, and flaws. Real flaws. This is a movie in which the characters make real mistakes, and that's okay, because it's part of the point (we'll get to that soon).
It's a Star Wars movie that really builds on aspects of Star Wars that have been left incredibly lacking in the past. Aspects like"¦
