I would love to spend more time improving my filter, but, in movies for example, the suggested movies to rate are all over the map... have you really thought about your demographic here? Movies from the 1950s aren't going to be the most relevant to early adoper Internet users. There should be a weighting to your random function or whatever you are using for "MORE MOVIES" towards the past 15-20 years.
I should also be able to pivot off of a movie to see what other movies people like, helping me discover new movies and further improve my filter from within these screens. You have this elsewhere on the site, but the first thing I jumped into was improve my filter, which doesn't have this or isnt easily reachable.
