And to those comparing TLJ with TESB: I find it easier to relate to someone that has a lack of self trust and was lied to and has his world destroyed, than someone whose failure was almost murdering his family. I actually think it’s pretty hard to relate to the latter.
Luke is far more relatable in TLJ than ROTJ in my opinion. Obviously once you get into specifics it falls apart in any of the films. But the Luke of TLJ is one that had a moment of weakness years ago and has regretted it ever since. The fact that he was tempted to kill his nephew doesn’t really make him un-relatable when you factor in the things that brought him there that have no analogues to anyone’s life (force visions, the dark side, etc.). It’s the broad strokes that are important.
