There is no why or how, only good acting.

Rating: 6/10 (2 March 2017)

Stand out performances by all three main protagonists(Watch out for Dafne Keen), its a shame the script or the director didn't give them anything to work with.
I see where the movie wanted to go, An amazing character piece like the title implies, but unfortunately the movie didn't get there.
Wolverines character has always been heavily rooted as a selfless guardian. The movie set out to embody this theme whole heartedly. The problem is this theme, which had the potential to be amazing, doesn't get explored like it should have.
When the movie starts we see Logan(Jackman) broken down. He's resorted to alcohol and later we find he is intentionally letting himself die(Even though it is never explained how, other than that he is somehow "poisoned").
This is where the movie flops. It's safe to assume that his character is falling apart because of his failure as the mutant races protector. His character has a long history of struggling to come to terms with loss. BUT THIS NEVER GETS EXPLORED! The closest thing we get is one line near the end of the movie somewhere along the lines of "Everyone around me only gets hurt".
We never saw him come to terms with his failure, to reconcile or to even acknowledge that this is what is destroying him. Instead the only progression we see with his character is that he once again assumes the role of protector when seeing young mutants in danger.
We could have seen it explored in his relationship to mentor Professor Xavier. The one thing they share in common, the protection of mutants and how Xavier weighs Logan on his achievements and not just his failures like Logan himself does. They almost had a moment sharing a kinship over their failure to protect in the farm house. But once again, it never gets there.
Or the endless potential with his relationship to his daughter, which I would say is completely flat. (Throwing the word "Daddy" as a last ditch attempt didn't work) Instead we see Logan being reluctant throughout 90% of the movie, without any explanation as to why.
Its such a shame because there was such a golden opportunity for us to see Wolverines character fully fleshed out and to see the inner workings of his self-sacrificing psyche. The regenerating man, who sacrifices himself over and over, endlessly protecting the vulnerable and having to live eternally with the weight of the ones he fails to do so with.
But we just don't see any of that in dialogue.
All we see is wolverine being reluctant like he always does then finally coming to peoples aid, and not the reasons as to why he does it or how it affects him.
Which is what the movie should have been all about.
