I think there's merit in both. One thing that is lost from choosing what you want to watch is that you don't get surprised anymore unless you want to be surprised, whereas with traditional TV you'd encounter things you didn't expect, or come across a movie you never heard of before. I think there's space for both.

Or to make another analogy, if you go out and sit at a bench, who knows what will pass by?
