Haha agreed G&G! Luke really isn’t inconsistent to his trajectory or the problem, Leia in a tree-house saying “Hold me!” is the far bigger culprit. I am on the same page with most that ROTJ may have some of the lower lows of the trilogy but does make up for it with some of the highest highs, most of which is the Luke/Vader/Emperor stuff.
It’s a bit jarring to get something as kid friendly as ROTJ after ESB though not totally out of character, but it never gets so stupid to me to take myself out of the good parts which can still give chills. In my opinion, when Luke throws down his saber and says “I am a Jedi, like my father before me.” it’s one of the great powerful moments in cinematic history.
