I’m personally pretty indifferent to ROTJ at this point. I see what’s “wrong” with it, but it doesn’t really bother me. What’s done right is good enough for it to even out for me.
Plus I’ve never seen the Ewoks as a flaw so much as a somewhat odd execution of a pretty good concept (Wookiees, like in the ANH first draft, or something similar probably would have worked better though).
