Personally, I don't like Netflix's streaming video model, I much prefer that of Amazon's but I would definitely like to see the price decrease. Having a large library of movies (mostly older, some fairly recent), doesn't do me any good unless it has the movie I want to watch at that time. I don't watch all that many movies so when I do watch one I want it to choose from any movie to do so, not be limited to a subset of movies for which they were able to negotiate rights to stream them.
I think the "buffet" model of streaming content works for TV shows a lot better since they're shorter and most people are more willing to watch what they consider a "sub-optimal" choice of a show than a movie.
