I don't wish to get into a conversation about whether violence in films causes violence in the streets -- I'd like to skim past that and look at it more positively; and ask--- do we have an opportunity to change the world, for the better, with the stories we tell? And how should we go about doing that? It's a tricky thing to approach. I remember watching 'Wall-E' in the cinema and being completely turned off because of it's overt messages about the environment. Yet at the same time I've watched many other films and enjoyed the political intent behind them. Does it come down to personal taste, or is there a way of storytelling that is appropriate? Do we know where that line is?
It's also worth addressing the fact that It'd be a shame to swing too far in the way of responsibility and political correctness. A film with absolutely no violence, no jokes pertaining to race or sex or sexual-orientation would be boring. It wouldn't be real life. Is it wrong to have pure violence? Is it wrong for Tarantino to rewrite the most important death in modern history? What responsibilities do we carry as people putting our creative ideas into the open?
