The idea the Jedi are bad is such revisionist history that all started with the prequels.
“Bad” ? No, but they lost by arrogance and blindness to their own power. In ROTS I really like the part where Mace just wants to kick Palpatine’s ass without any proof besides what Anakin told him.
Well, some of us hate the prequels and don’t really consider them Star Wars anyway. That’s where this fan division really started I think. If you grew up as an OT Star Wars fan, there was nothing bad about the Jedi. George turned into the billionaire and suddenly he didn’t want to make movies anymore about small little bands of friends rising up and overthrowing the existing order. His center of gravity changed and he wanted to start telling stories about political squabbling and the two trilogies don’t coexist well with each other. I mean, he introduced Midochlorians after all!
I was hopeful when TFA came out that Disney was moving away from the prequels and bringing Star Wars back to the originals. That shot of Han saying “Chewie, we’re home” and all the emphasis on practical sets and effects. But I guess it was probably nothing more than a ruse.
