I'll admit that I have had Netflix recommend to me movies that it thought I would rate at one star, and I have watched that movie and then rated it one star. Not only did their current system predict that I would watch that movie, they predicted my relative opinion of the movie's quality. And yet I watched the movie, and thus felt like their recommendation system served its purpose. I have to say that going into it expecting a one-star rating allowed me to set expectations for the film.

If they remove the axis of quality and merely opt for "will you watch this: yes/no", it will make it harder to select "good popcorn trash" versus "high-quality, high-enjoyment" to fit my mood.
