Has the algorithm used to generate "Top Picks Just For You" been changed recently?

So... I happened to look up some information on the Twilight saga a few hours ago; I visited the pages of all 5 films. Lo and behold, my "Top Picks - TV Shows and Movies just for you" recommendation list is now FULL of Rom-Coms, Rom Dramas, and Other Chick Flicks (as opposed to Horror, Thriller, Sci Fi.. titles, which it ordinarily has.) The (i) Information button says "based on your interest in Twilight, etc." I can only assume the algorithm has been changed to be biased in favour of very recent page view history, as opposed to our overall viewing and rating history. Please investigate.
