Because the complaint is actually more complex. It isn't simply that you are paying for stuff you don't watch, it is that you want to watch something good but there isn't anything good to watch. Then those other shows, the ones you don't want, look like they have pushed aside the things you are interested in. Netflix is different because in the streaming model nobody perceives one show as crowding out another. So those shows you don't want to watch aren't impacting your day and don't need to be removed.
But every popular movie on my TODO list is unavailable on Netflix, because they tend to produce their own content... After watching a dozen movies/series in the French catalog, there was no good content left to see.
From my perspective, Netflix follows a massive hot & cold pattern. Once a year or so, they'll license a bunch of great content, I'll watch a chunk of it, then a few months will pass before the next round of deals are struck and content made available.
My current "system" is to pay Netflix year-round and to subscribe to HBO Now when GOT is released (and catch up on other HBO content at that time) and cancel when it concludes.
I wish Amazon and Apple would get their shit together and allow/provide Amazon Video on Apple devices. That would fill in any gaps for no additional cost (I already pay for Prime for shipping benefits).
