Old Man Logan stinks. It's a mean-spirited comic without anything to say. It's a good thing that James Mangold's Logan borrowed some ideas and the idea of Logan growing old and junked everything else and actually went way further than Old Man did by actually killing off Wolverine. Millar's Old Man Logan borrows from Clint Eastwood's Unforgiven but it forgets that the whole point of the "retired outlaw going on one last adventure" is supposed to be a tragedy, a waste, a degradation. It's not supposed to be a cool comeback tour. And again why the hell is Hulk a cannibal, and an incesty-creep, what is that trying to say?
The concept doesn't even make sense. How is that Matt Murdock with his red hair sticking out under the mask, as glimpsed there, not aging when Peter Parker apparently has a grand-daughter who is in her late teens?
Most of Millar's stuff is bad and sub-par but unfortunately, it sells well. About the only good superhero comics he wrote for Marvel is Marvel Knights Spider-Man and I think working on Spider-Man kept him in check. When allowed to let loose in Civil War, Old Man Logan, The Ultimates, and UXM, he sucks. And don't get me started about Red Son.
As far as Ashley Barton is concerned. I don't especially care who her grandmother is because I have no interest or curiosity about what Peter's fate and that of his supporting cast is in the world of OML. Don't especially care for her either as a character.
Right now there's a story called Old Man Quill set in the same universe, and they decided to show what happened to The Thing (
