it's like the least political (and least coherent) of nearly all of them. every single star wars has had a strong anti-imperial stance, with the prequels shifting to basically an anti-authoritarian stance. The rebels were based on the viet cong for fucks sakes, according to Lucas himself. The prequels were anti-bush even during that awful window right after 9/11 where anything slightly critical of Bush was called unamerican (those that lived through it know what I'm talking about). The prequel jedi can even be seen as a pretty good analogy for the Democrats (from a old school liberal like Lucas), well meaning but ultimately a huge part of the problem. Meanwhile TLJ has what "anyone can be a jedi"? You mean like the hundreds we saw in the prequels? Every single one was an anyone, with the one exception of Dooku (he was a planet's dictator's son). I can't even think of any coherent message in TLJ. Meanwhile the rest of Star Wars was teaching damn important lessons about power and governing gone horribly wrong, all in a way that is both easy to understand for kids and enjoying for adults. Meanwhile TLJ has caused nothing but drama and arguing, no matter what you think you can at least acknowledge that.

TL;DR: the originals are pretty damn good actually, prequels not so bad either.

edit: this is just about the politics of it, I could go into other areas but this one has bugged the shit out of me the most
