The end credits he still has bone claws, so for 2yrs he's had bone claws and not sought to get adamantium back on them.
I feel the pacing of the whole movie is great.
I personally would've liked some nod to Origins. I get the internet hates it and I admit it's flawed but I've seen worse movies and think it's overly hated. Perhaps having Kayla in one of the dream moments. That way it kinda becomes a "women Logan's loved" type thing. Maybe the Kayla dream could even warn Logan not to love this girl(Mariko), bad things happen to women you truly care for.
