I think in hindsight i like Last Jedi the most because you expect Luke to be the hero, but all that stuff he says about the Jedi’s vanity, how the force is more than the Jedi. I also like how he threw away his lightsaber not because he is a coward but because he will no longer act out of anger, or use a weapon of violence.
Rey needs to find the strength to believe in herself, Luke was right she didn’t need him.
