We Don't Need R-Rated Star Wars - Music Free Static (064)

With the success of Deadpool, there's been talk of more R-rated movies
in the MCU and Star Wars. My question is "Why?" What does the
inclusion of excessive profanity, nudity, and gore bring to the story?
Star Wars as shown over and over again that mature stories can be told
in the universe without any of the things that would make it
R-rated. Does any of that R-rated nonsense improve the story?
