I defended TFA pretty hardcore because all the ideas they used were just EU (expanded universe) stuff that had been explored in the books. Believe it or not that whole Luke story that was used in TLJ was another one from the EU lol. it actually makes a lot of sense to me. Yoda in a sense also failed and spent years hiding and cutting himself off from the force in a similar environment. And Luke also sacrificed himself for the greater good, ala Obi Wan. I could see the nerd rage now had Obi Wan just given up amd let Vader kill him, in a recent movie, they’d be so mad and accusing the directors of assassinating the character.
My bigger gripe than anything is just that the characters went undeveloped throughout the entire movie and yeah there was a ton of potential for Finn, but instead he’s just kind of there. JJ actually did a ton of good work developing the new characters in TFA and it’s almost like we have learned absolutely nothing new to help us identify with their plight.
