How is the theme failure? The Supreme Leader was killed, the entire royal guard was killed, Captain Phasma is killed, the entire First Order rule is in complete disarray, the rebels had significant loses, but they escaped with their general and best fighter, and to top it off, Rey shows up in time to save every single one of the surviving members of the rebellion, with a shocking display of force powers, instantly becoming a new Jedi symbol to rally behind. I figured that would be the story that was being told, but nope, it's the story of Luke being told to promote loyalty to the rebellion, which makes a ton of sense. You gotta imagine the most legendary and well known person in the entire galaxy finally shows up, and the rebellion uses him to cover their asses, while he dies fighting an entire army by himself. How the fuck does this inspire loyalty across the entire galaxy towards the rebellion? It makes no sense.
Everyone is entitled to their opinion of course, I'm not trying to bash you for trying to spin a negative into a positive. To me it felt forced, pointless, and just all around bad. If you found meaning in it that helped you enjoy the movie more, than more fucking power to you, and I'm pumped for you tbh. I'm just too much of cynic to try and spin that shit as a positive lol.
