What gets me is how several companies and the masses are saying- Go Rated R on all superhero movies. Look at the success of Deadpool.
What they are missing is Deadpool is a natural foil for an R rating. With the exception of The Crow, I can't think of an R that did well (300 if you consider it a comicbook movie).
Keep my hero movies PG-13 unless the characters call for it.
