When the original Deadpool arrived in theaters, it was a breath of fresh air. Comics fans may have already been familiar with the smart-assed “merc with a mouth,” but in the context of modern superhero movies, both the character and the self-referential style of the 2016 film were a subversive delight. Deadpool's creators clearly knew how silly superhero movies had become, recognized that audiences also knew it, and mixed it all up into an R-rated romp that brought in more than $780 million worldwide, while costing just a fraction of the price tag on an average DC or Marvel tentpole.
