Ratings: Display relative movie ratings

I would like to see the rating of a movie as it compares to others in your database. For example, if a movie has a 6.2 rating, what percentage of movies are rated higher 50%, 70%. The absolute rating is more valuable if a relative rating is also presented. It would be great if the relative rating could be done by type of movie as well. For example if a movie had a 6.2 score and that puts it in the top 70% for all movies, but top 60% for dramas. The UI would be really cool if it were graphical.
