I have a bad feeling about making it an R rating. I personally don't care, but I know that it won't benefit the film makers if they're worried about making money. They'll loose some of their audience. The film is still guaranteed as a success, but they'll make more money if it's PG-13.
There are two reasons to make films, however. There's the common reason, and that is to make lots of money. The other reason it because they see it as an art form, and they just want to make their masterpiece. Whenever a painter wants to make his masterpiece, he tries to make the painting as close to his envisions as possible, regardless if everyone else likes it. Scott should be able to do the same thing. If he wants his film to have certain scenes, it should have those scenes. It's his film. Unfortunately, the film industry doesn't work that way.
