That being said, just because Marvel doesn’t need the Black Widow movie to be R-rated doesn’t mean it shouldn’t be.
Admittedly, chances aren’t too strong that the Black Widow movie will be R-rated, and we shouldn’t expect it to be because Marvel simply has no need to do that.
It may be just a rumor, but the Black Widow movie should be R-rated.
It should be stressed that this is just a rumor at the moment, and even if an R-rated Black Widow movie was discussed, that is no guarantee that will be what we ultimately get.
