Once you’re committed [to a TV show], however, there is trouble on the horizon. There are two possible outcomes. The series keeps up its quality and maintains your loyalty and offers you years of enjoyment. Then it is canceled. This is outrageous. You have lost some friends. Alternatively, the series declines in quality, and this makes you unhappy. You may drift away. Either way, your devotion has been spit upon.
It’s true that there is a third possibility. You might die before the series ends. How comforting is that?
With film you’re in and you’re out and you go on with your life. TV is like a long relationship that ends abruptly or wistfully. One way or another, TV will break your heart.
