The more I think about it, the more I appreciate what RJ did with this.
By amplifying the idea of the Jedi as a fatally flawed dogma, it turns the triumphant finale of the Original Trilogy into a threat. With The Return of the Jedi, the galaxy is forced to endure yet another war caused by this religion.
And so The Return of the Jedi becomes the giant looming question, the impossible task, the paradox that the final trilogy must solve.
Again I completely disagree. The Sith cut down the tree of the Jedi. That tree may have had some rotten branches, but at it’s core it was sound and healthy. Luke was a seed from that tree. That seed was planted, and was meant to grow into a beautiful new tree. Not the same tree, but it’s based on the same genes, the same basic values. That’s what the ST should have been about, evolution, the connection between the past and the future, not the past must die.
