>2. We've started expecting "must-see" shows and movies. You want to watch The Pitt, and then are mad that you need to get HBO or whatever and can't just watch it on Netflix. Perhaps you could browse Netflix and find something you'd like, but you have your heart set on a specific show.
>(2) is on us a little bit. Cultural monoculture is not good. Following the herd is not good.
I don't think this is it. People just want to be able to watch things without too much hassle and without paying too much money. Some people will enjoy following the latest trend, but there are always many more people not watching any particular show than are watching it.
The fact that torrents make it so much easier to find what you want shows that there's nothing technically difficult about this. It's all caused by stupid profit incentives which make the consumer experience so much worse than it needs to be.
