I use Netflix almost exclusively (Amazon Prime also), and though I also joined for movies, I do tend to watch mostly TV shows on it recently because I can watch episodes that I missed of series that I enjoy or whole seasons of things I never got a chance to watch. They have the content, so why do I need cable at all? Oh wait, I got rid of cable because Internet + Neflix is about 50% less expensive (for relatively fast internet too) than ANY cable service.
I can honestly say that I was paying a pretty decent amount for cable and realistically only watching a few regular shows and the occasional movie. That is kind of pointless. And to say "when there's nothing on cable" is just plain blank, because other than the big Emmy series, there really ISN'T much to watch on cable. If I don't like it on Netflix, I can at least find something else I like as opposed to cable where you are pretty much going to have to channel surf unless you have a bunch of stuff you never watched on the DVR - at which point you are doing practically the same thing as watching a streaming service.
