Who says it’s something they gotta learn before they die?
Apparently George does because it’s an ability in the PT.
Why bring the PT into this? It’s notorious for incorrectly (or implausibly) portraying things.
Because they’re canon. And even if you leave them out of it there’s still no explanation as to why Anakin turned into a Force Spirit. You’d have to assume that all Jedi are just taught that.
They are one with the Force. There’s your perfectly good explanation. Why does it need to be taught to someone like a technique of some sort. This is religion we’re talking about. That’s what I hate the most about the PT portrayal of the Force. It’s no longer treated like a religion that a select group of Jedi (monks) follow in good faith.
That’s fine…I just wish they hadn’t made it seem like all of the darkness inside him dropped instantly. Maybe if Kylo Ren renounces the Dark Side (which I highly doubt) they could have him atone for his misdeeds.
The purpose of that whole ending was that Anakin overcame the darkness inside of him and redeemed himself. Luke could sense the good in him, and was able to bring it to surface, in spite of Vader claiming it was to late for him. Nothing that needs an answer is left unanswered.
