For years, it seemed like a Deadpool adaptation would never get made. When it finally came, it blew its competition out of the water and made $783 million, making it the most successful R-rated film of all time.
After witnessing Wade Wilson's disastrous debut in X-Men Origins: Wolverine, comic fans rejoiced to see the Merc with a Mouth on the big screen depicted just like his comic book counterpart. Audience members not familiar with the comics loved Deadpool as well since they'd never seen a superhero like this before: sarcastic, hilarious, absurdly violent, and fully aware he was in a movie.
Here's the problem: Deadpool blindsided critics because he was unprecedented, and came with a built-in shock factor. So what do you do with a sequel? You can't just do more of the same - Wade's novelty will have already worn off. Luckily, Deadpool has had hundreds of crazy adventures over the last few decades.
However, there are some Deadpool stories from the pages of his comics that are too extreme. Too insane. Too...well... too silly. Don't worry, though, we will definitely see Cable butting heads with the Regenerating Degenerate and we will finally witness Domino kicking ass. It's just that there's a few scenes from his past that are too crazy even for Deadpool.
