To me, given the choice between a Luke who destroys walkers with the force and a Luke who faces them down without any killing, there’s no question which is the one more true to his character.
Luke should have fought against Kylo Ren in person and his confrontation with the walkers should end like Dark Empire(size matters not…). He never, never should have abandoned the jedi order, that’s not Luke.
I often wonder if, had the PT come first and the OT came out decades later and the scripts were all more or less the same, people would say this exact thing about Obi-Wan and Yoda in the OT.
“They never would have given up and gone into hiding! That’s not Obi-Wan/Yoda!”
I can just imagine the reactions at the end of ROTS. Oh they’re just hiding for now. They’ll be back soon. And then when they see the OT. What have they been doing for the last 20 years? Nothing at all?
