No way under the sun that Lucas treats Luke the way Rian Johnson did. He may have went away to mourn for a short time, but no way no how, not a chance in the world, he would have fully de-construct his beloved franchise hero the way Johnson did.
The entire issue with the Disney ST is they felt the need to be subtractive with their story telling. All they had to do was be additive instead. Treat the legacy characters with respect and add your new generation of characters for the new generation to fall in love with. The only character that was respected and treated correctly was Leia. Other than the stupid Mary Poppins flying scene she was pretty well respected. So is it a fluke coincidence that the two OT male leads both went out as dead beat losers?
