I joined Netflix way back when, before they had anything decent to stream online. I also have an Amazon Prime membership, HBO Go, as well as a Hulu+ subscription. Of the four services, Netflix held the most promise and is the one that underdelivered the most. I love that they don't bother you with commercials. I love that their service is actually fast and available. Their app on Roku is faster than Hulu's and always seems to select better video quality if bandwidth is constrained. However, I end up almost always reaching for Hulu. Netflix just stopped expanding, and in some cases started losing content.
On the plus side, they have entertaining shows such as House of Cards and Orange is the New Black. However, I think at this point Hulu and to an extent Amazon has them beat in terms of new content from traditional sources. I will continue paying my $9/month, for now. However, I do hope they improve enough to justify spending money on them.
