It’s hilariously ironic that George Lucas originally conceived of Star Wars as a throwback to the old movie adventure serials, and then criticizes TFA for being a throwback to the Original Trilogy (a throwback of a throwback).
Yes, visually TFA is extremely similar to the Original Trilogy (maybe too similar), but visual distinctiveness by itself does not make a good movie, which George always seems to be implying. For all the visual distinctiveness and new digital technologies used to make the Prequels, they’re not even close to being as engaging as TFA.
