See https://www.criticker.com/explain/ -- it works sort of like what you're suggesting. You rank movies from 0-100, which is different from rating them. Your percentile ranking scores are compared to other users' rankings, and then it can suggest movies that it thinks you will rank highly.

IMO the real problem with something as subjective as books or movies is that even completely honest, well-reasoned reviews are going to be all over the map. My review of a Pride and Prejudice movie is going to be maybe 3/10, but my wife would give it 7/10, while we have the opposite reactions to something like The Hunt for Red October.

I don't care about reviews from experts or the unwashed masses. I don't even really care about reviews that much -- I'm more interesting in ratings from people who like the same kind of stuff I do.
