I'd be happy to pay by the hour.
In the streaming business you lure people into paying more than they otherwise would (on average - your mileage may vary) by giving them a feeling that they get so much content for the money. Even though in practice they then actually find a quite limited amount of content they actually enjoy. Also there's the typical trick of subscription services that "you can cancel at any time (but you wont)", which makes the purchase feel more affordable.
Maybe that's my bad attitude and I should pay what it costs. Or Amazon is pricing these too high for some reason.
Also, I'd need to see the first few episodes of any show before I pay up. I start a lot of shows, and hive up on most of them.
