Whats the cost of media?

So I was talking with a friend and she was teling me how this movie she watched was 'sooo goood'. I know the gist of what the movie is about and know it has a lot of violence and other content in it. It just made me wonder, what is 'good' media? What is the cost we pay for being entertained? Why is watching/listening to media that does not agree with our standards become so appealing when its for the sake of being entertained? Is what I am watching worth the effects? If you ask yourself that, is standing up for it worth the cost of offending someone? Possibly offending your family? Whats the balance and how do you not offend? Just some food for thought!
