Let's not forget the original plot for The Force Awakens.
The First Order and The Resistance were fighting for "map to Luke Skywalker".
how do you even have a map to someone that could be moving from place to place? And why would Luke intentionally leave a trail for someone to track him down, for him to react the way he did in The Last Jedi.
You could put the blame on JJ Abram for that retarded plot or you could blame Rian Johnson for the follow up arc. The blame really goes to fukking Kathleen Kennedy for overseering both films and allowing that nonsense to happen under her watch.
