36 year old fan here: I felt like this Luke Skywalker definitely fell in line with the Luke we grew up with. Abeit one who made a mistake and can’t help but hide in shame.
The funny thing is: I was expecting a curmudgeon Luke when TFA came out. I mean, they pretty much set it up in that film. Jedi school gets wiped out by Kylo, Luke runs off to find the Jedi temple (looking for answers?), and doesn’t find solace and decides that life isn’t worth living.
I totally agree! It surprises me that people were surprised by the Rey/Luke pick-up at the top of this movie as compared to the end of TFA. As far as I saw it, that was exactly what I was expecting! When he tossed the lightsaber over his shoulder, it was shocking but at the same time, exactly what I figured was going to happen.
