I dunno, really. It’s a tough thing, ya know? Why does a Marvel movie need to be rated R? What does having swear words, nudity or excessive/gory violence (some or all of those) do to elevate the movie? From a story standpoint, does it help? Does it make it a better movie?
Also, an R rated movie will most likely make less money than a movie rated PG or PG-13. I like that we make movies that families can go see and enjoy on different levels. An R rated movie may stop parents from taking the kids to go see the movie.
The Wolverine kind of answered that question with making an Unrated cut for the Blu-Ray and DVD release. Even though it was toned down for the theatres, I think the Unrated edition actually fulfilled my boyish love for violence and intensity.
When it comes to theatres, I think Marvel can tone down as much as they want so that they can keep the image and profits they want. But when it comes to a home release, I think that there should be a choice to choose Marvels version or the Directors version.
I think that is what will happen with a Deadpool movie, if it ever gets on its way. Deadpool is funny and flashy enough to hold down an audience without getting too intense for the viewers, but I do think that there should be an Unrated cut that will allow for the people to see the Unrated Deadpool movie that they’ve been waiting to see, full of the blood, gore, and sleazy humour that we’ve grown accustomed to.
