Rating movies with half-stars.

A lot of the time when I am rating a movie I will want to rate it a half-star, so something like 6.5, 7.5, or 8.5. The problem is that because you can't do that so I will just round it up to a whole number so that list would go to 7, 8, or 9. My proposal is to be able to rate half-stars on IMDb so that people can make more accurate ratings.
