While I like the idea of Luke’s final moments actually accomplishing something, the idea that he’s an inspiration to everyone because of Crait never made sense to me. He’s inspiring like a dozen remaining members of the Resistance that are already die hard fighters and believers in the Jedi, they barely see him in action from a mile away, as far as they know he got killed by Kylo Ren, and he didn’t actually train Rey at all. Where is the inspiration coming from?
A symbol of hope arriving to confront the bad guys and to allow our heroes that were on the verge of defeat to escape.
