Luke did something we’ve never seen any other Jedi do before. He projected a solid version of himself across unimaginable distances and could interact with Leia and even Threepio. That had to come with a price. In the end, Luke saved the day one last time and went out a hero.
I didn’t get that from the movie at all. If that had been communicated more clearly to the audience it might not have felt so insulting to me.
That’s immediately what I thought. Died of exhaustion after that performance.
