It seems that ROTJ not being a very good movie is slowly becoming not an unpopular opinion?
It has inched closer and closer to that over the past decade. This realization was partly born out of the more analytical side of the prequel backlash, re-examining the “Ewok movie” and realizing it wasn’t as good as remembered. I’ve got no problem with the Ewoks, it’s more that I find the Jabba’s Palace set piece painfully slow and too isolated from the rest of the movie.
My awakening to ROTJ not being as good was watching 4K83. Divorced from all the Special Edition changes and subpar mastering, the cinematography looked bland (my biggest issue) and the pacing felt off. It doesn’t live up to ANH and ESB, but it’s still a more satisfying trilogy finale than many.
