I would have to firmly disagree that there’s little to take away from TFA. I believe the issue lies in older fans trying to insert their childhood memories and feelings into the newer films. It won’t work, and never will!
The prequels, despite being arguably junkier, still impactful on my childhood just as much as the OT. My imagination flourished. It greatly fueled me to draw, make things with my hands, act out what I saw on screen, and seek an amateur understanding of effects and film editing. Things are way different in the perspective of a child that an adult cannot see. Part of growing up though is realizing things cannot be the same. I would love to return back to child me where I could view all six Star Wars films equally, but realistically, that cannot happen.
Star Wars, even after all these years, will continue to ignite imaginations of children. Prequels couldn’t destroy Star Wars and neither will TFA.
As a quick side note, I arguably think Rey is just as deep as Luke from A New Hope. Luke yearns for adventure and freedom. Rey seeks psychological freedom from the past to move on. Both characters have something relatable.
That write up basically is saying the new films are ruining the childhood memories you had. This isn’t for you then; it’s for a new generation. Continue to watch if you want, but stop expecting it to reconstruct your past experiences. The Spirit lives on in different forms in the eye of the beholder.
