You can’t please everyone when it comes to resurrecting one of the most beloved franchises in film history. So if you were disappointed with how Star Wars: The Force Awakens ended, maybe you’ll prefer the How It Should Have Ended alternate finale featuring Kylo Ren getting his comeuppance.
Anyone else think Luke may not even be that much more powerful than Kylo? It’s pretty clear that Kylo wrecks shit. Even when he’s got a wookie blast shot in his gut, he’s still able to fight both Rey and Finn. Plus, he can stop laser bolts in mid-air. Compound that with the possibility that Luke is getting older and he probably taught Kylo everything he knows, and you don’t have such an easy fight. My guess is Luke's powers are no match for Kylo, and even if they were, he doesn't have it in him to fight his own nephew and pupil. That has to cloud his feelings and affect his balance with the force.
