For some reason people think of them as the new hot thing, but the reality is they have been around for longer than Google. With competition in the streaming video market only getting hotter, I can't see them going anywhere but down. Any one of Amazon Video, Hulu, Disney, or HBO could unseat them.
The growth expectations implicit in their 200+ P/E ratio seem way out of sync with their actual potential. If I owned Netflix stock I'd be selling it all now.
