5. Wolverine 3 Is Based On Old Man Logan, And That's A Dark Story
Old Man Logan is arguably the most famous X-Men story-line of all time, with good reason. It took a vast array of characters to a whole host of deep, dark places - and Wolverine was among them. The arc he's faced with across this 8-issue series is gripping, drenched in blood, and can only truly be captured by an R rated Wolverine 3. For starters, Wolvie slaughters pretty much every single one of his fellow X-Men while under a trance-like influence, causing him to flee and abandon his superhero persona completely. He then proceeds to decapitate Red Skull using Captain America's shield, and murders the entire Banner clan before killing the big guy himself - by bursting out of his stomach, Alien-style. If there's any aspect of that description that you think sounds child-friendly, then you should probably visit a psychiatrist. Just look at all the gory detail the comic-book provides - impalements, knife wounds, eyes gouged out - and it's clear that there's only one way this story-line can be faithfully recreated on the big screen.
