But Luke changes his tune after his conversation with Yoda, returns to save his friends, WITHOUT killing Kylo, leaving the door open for his possible redemption, and goes out expressing hope that Rey will get the Jedi going again after all. He strayed for the seven or so years between Kylo’s fall and the start of the ST, but by the end of the movie his faith in the Jedi is restored. The beginning of the movie deconstructs the whole Jedi thing, sure, but I don’t understand how people aren’t seeing that the last act reconstructs it.
