While this may not be applicable to goodfilms, a 2-dimensional system is harder to brand. As in, "Two thumbs up," or "90% on Rotten Tomatoes." There's value in a single understandable number.

I wonder if there's a measurable value for the system. I care about discovery, so I want a site that can recommend me movies that I wouldn't normally think about. How many more movies would this system recommend to me?

A lot of times, I don't care too much about accuracy as long as the system isn't too far off. This is simply because the cost of an inaccurate recommendation isn't too high when I can stream it on Netflix.

I like the idea of providing more data for people to make more accurate assessments, but I don't necessarily believe optimizing for accuracy optimizes the value provided to the user.
