Netflix is just a movie service. And it is a movie service that hasn't gotten any better for a very long time. The fact that I have to spend a lot of time finding content to watch and Netflix mostly showing me the surface layer of content over and over again is extremely frustrating. It just isn't a good experience. They are about as frustrating as every other service on the market because they deliver an experience that isn't anything special: it is just as bad as every other competitor.
If they have no ambition to deliver a better service than everyone else, then why would they attract more users, and more importantly, have more users pay more for their service?
Right now Netflix is an acceptable service, but nothing more. They still have some way to go on quality. And if they started becoming the company that dares to do things a bit differently, and to do things better, this could be a platform to launch into other areas.
