I see an opportunity here. Is there already a recommendation service around that takes your rating profile into account? Apple has their 'Genius' system, however with respect to movies rentals I think this is lacking a bit: Movies I want to rent are usually movies I only want to see once, not gems like Godfather or Constant Gardener. A personal rating service would have to pose you targeted questions about your movie preferences and drill down into your personal taste.
