Were Yoda and Obi-Wan not ‘broken’ by events earlier in their lives? It would seem Luke is too in TLJ, and understandable given the circumstances - not forgetting his path to a change of heart towards the end of the film - sacrificing himself to do so.

For me, I like it more after I left the cinema. The more I think about it - and I am, weeks after it’s release - the more I’m understanding it and appreciating it.

(That’s not to omit the parts I personally thought didn’t quite work - yet I never went in expecting a perfect film - I’ve never seen one yet. Well, there was that one short film on pornhub…)
