That's true for almost any streaming service. I tried both Netflix and Amazon's offers, both had very little content I wanted or if it had then only a few seasons (in one case starting at season 5 and then not having the rest of them either).

And I totally blame Hollywood and the Media Industry, esp. Disney, for making hostile exlusive licensing deals.

In many cases, I cannot even watch a movie until it's dubbed in my language, even if I don't want to watch it dubbed but in OAT. It's frustrating. And then it's also likely on the streaming service I currently use, but on another one.
