Proper, memorable deaths and finales are things that are rarely given to superhero fans. Yeah, demises are handed to us copiously. Every member of the Marvel Comics universe has died in someone else's arms at least once. But only about one out of ten ever feels like it really means anything, because due to the nature of comics, you can assume that the character will show back up in a big, dramatic splash panel the next year. The same goes for movie series. The Dark Knight trilogy is one of the best-reviewed things in the history of everything, and the ending of that was basically a trembling fart in the sunset. And it certainly didn't help that some new dude showed up as Batman less than four years later to star in a series that was created to replicate the success of another company's series.

This movie should've made a trillion dollars. Should've.
And if the X-Men franchise had been one big stupid success after another, this might've actually meant less. But just like the fact that Wolverine, in these movies, has had just as many kickass moments as he's had moments where he's gotten the shit kicked out of him, Hugh Jackman has stuck around through the good times and the bad. Remember X2: X-Men United? How good was that movie? Remember X-Men Origins: Wolverine? I do! I wake up sweating in the middle of the night, and I do.
And while it's easy to get bitter over the fact that Wolverine turned a lot of these movies into The Wolverine Show, Feat. Other Less Important Freaks, Hugh Jackman, like his character, has held them together at their lowest points. Jackman isn't the greatest performer that the world has ever seen, but he's never not solid, and when you collect a team of actors and have to deal with competing egos and salaries and contracts, solid is what you need the most. In the same way, Wolverine will never have the awe-inspiring power of someone like Magneto or the sheer radness of Nightcrawler, but he's like a wrench. Sure, it's just a wrench, but you'd be surprised by how much you can do with a wrench.

When you need someone to make a feud with Sabretooth feel emotionally effective, you call Hugh Jackman.
In Logan, both Wolverine and Professor Xavier seem to be losing the powers that helped them to fight off mutant terrorists so successfully for the past 60 years. Age is getting to them, and while keeping age in mind is only a suggestion in the comics, it's something that affects the crap out of actors. Ten years from now, Hugh Jackman is going to be almost 60, and he's already surrounded by actors who are younger than him, have better contracts than him, and can handle the effects of a constant IV of protein shake better than him.
