While it is run from the same recommendation engine that operates elsewhere on the site, that panel is static not dynamic, so can't take your ratings into account. As I say there it wouldn't be so bad if there was a link on to directly access the recommendation engine where you could input a film ID and then filter out anything you've rated, but I often find I've rated all films or it offers me onces I've no interest in seeing at all (another part of the discussion, as IMDB must hold a "not interested" list too).
