So I just watched The Dark Knight and The Dark Knight Rises back to back, and I think that if TLJ treated Luke the same way TDKR treats Batman, TLJ Luke would be much more acceptable to me.
For example, at the end of both TLJ and TDKR, the older hero passes on the torch to the pupil, but while in TDKR Batman wins the war and finally provides peace a second time, Luke… just passes on the torch and says “hey boyos, now that I’ve given you guys hope please clean it up!!”
