Back when you had TV on a specific schedule, you were forced to watch things as they were. If a show was clunky, well you didn't have much choice in the matter, it was watch that or change channel or go outside.

With on-demand stuff, you can just completely skip over stuff you might actually like because the first few episodes are clunky. Why should I watch something clunky when I have the choice to watch something I know is good from the start?

...I'm still not watching One Piece though, I don't care how good it gets later.
