Many find that television today with the ambiguous endings instead of happy ones, the increase of anti-heroes instead of just heroes, and that many ways that people of power (politicians, police, etc.) be the antagonist or morally ambiguous instead of just good as a bad thing. I happen to think the opposite. What television today helps show to us is that nothing is ever really black and white, including people. It helps show that maybe something isn't as good as they seem instead of bringing a simple narrative that might lead some to believe in a simpler worldview.
Back in the 1950's television was simple and many people did not know many problems going on in America, such as racial prejudice, sexism, and many other problems that was not in the public eye. Today there are so many t.v. shows and channels that are fine with shows that show things that show another side of life, whether it looks good or not. People today are then faced with looking at issues that they may not have known otherwise.
Of course there should be some responsibility in watching television, in the sense that they overblown their stories because it is entertainment. It should always be up to the individual in watching television and not everything in television should be taken as fact but it does bring up different thought.
