The intent was there, even if it was poorly executed on. That lack of coherence is one of the most frustrating elements of the new trilogy for me. It had a lot of good ideas but no sense of direction.

It wasn't executed on at all. The story was not about Luke, it was about the new class. Which could have been fine as well, but they ruined Luke's character with no explanation. Some people care about that.
