logan is the original stone cold steve austin. regardless of how talented he actually is/isn't, he's relatable in a way everyone can understand/aspire to understand. at the end of the day, it's no fukks given. no different from batman really (minus the murder).
the trick is... the best writers kno how to channel his popularity. b/c no matter how much we all love him... he's basically an indestructible midget with indestructible steak knives for extra fingers. in fights that really matter (apocalypse, thanos, magneto), he should be irrelevant. but he fights anyway. and will always get his hits in before going down. THAT'S why we love him.
but now... he's so popular... that like batman, he's capable of shyt outside his power base. logan is a hitter. but he's not a heavy hitter, if that makes sense. he's a daredevil-level character in terms of power-set, with superman-level power in terms of charisma.
logan SHOULD BE the dude that (if he manages), murks thanos because thanos already murked him, killed everyone else, then walked into a set of adamantium knuckles because he forgot logan gets reallllly better realllllly fast. but more often than not, now, he's the dude that fights someone like thanos to a standstill, even tho thanos could kill him (temporary) from a football field away.
old school writers understood this. the only new school dudes who seem to get it are remender and whedon. logan was THE MAN in their books. but at the end of the day? when he overstepped his limits? he got fukked up quick.
lol. in astonishing x-men (og version) dude crept up on cyclops and emma in bed, started talking shyt about jean grey, and got eye-lasered out a window three stories up. THAT'S logan.
so basically... wolverine's a side character with main character screen presence. everyone loves him for the presence in the face of his own limitations. but they forget he's most effective in a supporting role. which is why a lot of people also dont understand his popularity. because he's portrayed as galactus, when he's really just plain old logan.
