Yeah, Wolverine is over a hundred years old now and doesn’t age because of the super serum they gave him so that his body wouldn’t reject the adamantium skeleton.
But as far I can tell, Hugh Jackman does age.
I think my favorite X-Men movie with Wolverine was the death of Jean Grey. Super Hero movies do many things well, however, dramatic scenes are where I usually find reason to criticize. Maybe it’s beyond the skills of the actors, or the suspension of belief required for the fantasy world premise is in conflict with accepting the “reality“ that superheroes can bleed. It may not be Oscar worthy, but Hugh Jackman took this scene as far dramatically as was possible.
