I do say no to things that I think are completely gratuitous.
The scene that has raised the most objections in 'The Interview' is at the very end, when Kim's head dissolves into flames. To me, it feels gratuitous.
I think the last one would have to be The Godfather because it was such a powerful story. There was lots of violence in it but I could take it because I thought there was a reality to it. It wasn't gratuitous, it was just these guys' story.
I don't ever want to be gratuitous, for the sake of being gratuitous, but when it serves the stories and the characters, it's nice to be able to do that, realistically and with credibility. You don't want to do it for the sake of it, or shoe-horn it in. But, it's a good tool to have in the toolbox.
Did Google need to make robot cars in order to make Streetview work? Absolutely not. It's the equivalent of saying you need a walking robot in order to push an upright vacuum cleaner. It's gratuitous robotics!
We are providing a platform to creators who are expressing their emotions; they are expressing what they are feeling - fears, joys, terror. That's what art is about, and we don't want to censor it, but neither would we permit violence which feels gratuitous or glorified to be on our platform.
