I agree about the hilt. Luke using his father’s saber at the end never really made much sense to me though. Sure it’s the “Skywalker saber” passed down from generation to generation, but Kylo literally saw it get ripped in two a few scenes before. Wouldn’t that be a dead giveaway that Luke wasn’t really there? Or at least a huge hint that something wasn’t right about the situation? Plus, I kind of like the symbolism of him showing up with his green saber to use it to right the mistake he committed with it in the past.
