This idea has probably been thought through a hundred times already, but I'm pretty new here so I wouldn't know.
I was wondering if it could be possible to implement the ratings given by the user into the movie info box. It would be very entertaining to browse through, for example, NES movie list while comparing your rating to the overall rating on the fly so that if the difference between them has changed a lot over the time, you could return to the movie and track down if you missed something before or should completely re-evaluate the given rating. That would also point out the unrated movies so you wouldn't have to browse them separately.
It would only be an esthetical feature to please the few who rate movies, but I think it would encourage users to rate more movies and watch them more carefully. Does this idea have any echo?
