re: Yoda and the Clone Wars era Jedi Council were really not competent at their jobs at all

Their incompetence pushed Anakin into becoming Vader. Their doctrine of “no attachments” was needless and led to much suffering in the galaxy. Anakin was having nightmares about losing a loved one, and the Jedi response was “learn to let go.” When clone wars showed that Obi-wan was passive while his love was murdered right before him, you understand Anakin even more.

Luke in the OT was more open to attachments against the advice of yoda and Obi-wan, and it was good. It made him stronger. It saved his sister, his friends, and his father.

I really thought the new trilogy was going to address this, and have Luke being balance to the force in this way by incorporating emotion and some dark side ability into a new way of the force, bringing balance. The trailers hinted at that with “it’s time for the Jedi to end.” It seemed promising that he had learned from his experiences and would improve on the old Jedi ways. Instead of course we got The Last Jedi.
