Deadpool could definitely be done PG-13, I'm not really arguing that. Done as good as this film? That's a far stretch. Without the R rating you lose a lot of marketing, positive hype and the creative team that was seen to get people to the theatre and peak interest. I don't see another team or film matching what these guys did. This just broke too many records and had solid buzz that was dependent on the rating. You would have to strip it away of all that. Which would no doubt lead to a lower box office.
