The video essay is too simplistic.
Star Wars isn't a Western.
It can have moments that resemble a western but it's a war epic which touches on every trope in cinema and literary fiction (Biblical epic, medieval romance, Jidaigeki, Western, ancient myth, Scherazade, Dumas, Shakespeare) but war is the centre.
It's Star WARS not Lone Star.
The beat up second hand universe only applies to the beat up second hand things in it.
In the OT the Imperials and the Bespin denizens had access to new, dent free stuff.
The Rebels and the denizens of Tatooine didn't (they were poor and/or had to make do and mend).
Covering new things with dents and scratches is stupid.
The problem with the PT isn't that it's set in the city or in the senate (ANH had conferences and was largely set inside a giant metal fortress not that different from a stone temple or a giant parliament).
The problem was the story was boring and badly written and badly acted and directed and designed.
Harry Potter has libraries and conference rooms and parliaments and when it is good it's good because of the story and the acting and the direction.
When it's bad it's bad for the same reasons and the same is true of Star Wars.
The cutesy aspect does need to go though.
Many of the aliens from ROTJ onwards look like they would be right at home in an Oddworld game.
