On ROTJ the childish stuff hides Luke’s darker motives and tactics.
If you really look closely, from an adult POV, you notice that he uses the force to manipulate the Ewoks.
When 3CPO is telling the story, that’s Luke mind controlling, both 3CPO and the Ewoks.
Immediately after, they are accepted into the tribe, with the Ewoks sacrificing themselves in the battle.
So yes, Luke is not a nice guy in Jedi 😉On TLJ the dumb childish stuff highlights Luke’s darker side.
So it’s in your face, but it was there before.TLJ’s problem is not Luke, is the poor B story that makes little sense and is not integrated with the main one.
If you remove the silly stuff from both movies, Luke is consistent.
When has anyone been able to use mind control on a droid?
