The Jedi robes thing infuriates me.
As a kid, the single most iconic image that said "Return of the Jedi" to me was Luke dressed in what we were clearly meant to believe was a Jedi "uniform" - black, militaristic, but with a distinctly priestly touch. The film's title referred in large part to the return of the Jedi Order, as well as the return of Luke himself as a Jedi, both of which were represented visually by Luke's bold decision to dress in the distinctive uniform of a Jedi, first seen in the hologram where he introduces himself as "Luke Skywalker, Jedi Knight."
But if the Jedi uniform is just the generic brown robes worn by Tatooinian men, then what the hell was Luke weaking in ROTJ? And why was he wearing it? It's been reduced to a one-note visual metaphor for Luke's potential fall to the Dark Side and has no sensible in-universe explanation (apart, perhaps, from being an attempt by Luke to cosplay as his own father).
I always wanted the PT to give us the image of legions of black-clad Jedi fighting armies of white-armored Mandalorians. Instead we got... well, we all know what we got, don't we?
