Still hoping they do Wolverine as a proper antagonist. I mean, Hugh Jackman eventually won me over, but from the very start I was like "Oh no...what are they doing to Wolverine!? He's totally different!" The films pick up from the modern version of Wolverine: a team player, leader, and mentor. The guy who's supposed to be hard-as-nails but nearly always has a kid sidekick nearby.
I'd love to see the MCU do this original Wolverine: honestly an @$$**** most of the time, the kind of guy who's that Libertarian you can't stand getting in philosophical arguments with. Short, squat, heavy, dirty, smelly, rude, aggressive, nearly psychopathic... a tremendously dislikable character that everyone keeps around purely because he's saved their asses and been there when they needed him. He's that friend always getting the other guys into fights they don't want to be in, the one they all make excuses for and hang out with out of obligation and history. He'd bail you out of jail, but you wouldn't trust him alone with your stuff, or your girlfriend.
Basically totally the opposite of the characters Marvel wants to put in their movies now.
