Here is another site that has proven some worthy suggestions for me in the past. http://www.nanocrowd.com/
We think that why movie recommendations are so hard is because people might like the same movie for different reasons. For example, if I told two friends that I liked the movie "Titanic", and asked for a recommendation they might separately recommend "The Perfect Storm" and "Avatar". Two very different movies, but both would count as good recommendations for different reasons. The problem, is that when a person recommends a movie to you, they have already filtered it according to what they thought was interesting about the movie.
Having said that it is still the best way to discover new movies. We believe that easy to use semantic browsing is a good middle-ground for any information discovery.
nanocrowd is very cool. I have not heard of the company before, but they have a very interesting take.
