So not only does my little idea exist, but they’ve solved some of the problems I thought I’d have dealing with films a user hasn’t seen. Flickchart takes a Hot Or Not approach to rating movies, and gives you a way to skip movies you haven’t seen.

I’ve been playing with it for an hour or so and it seems to be building a pretty good profile of the movies I like and don’t like. Check it out: http://flickchart.com.
