No, it must be more complicated than that. If they were just consistently popular with a specific demographic, it would be easy to predict - the problem seem to be that even if you like Lost in Translation, you might still hate Kill Bill, or Fahrenheit 9/11.
After signing up for Netflix last month, I realized that I am one of those users that the algorithm writer's probably hate. I usually vote things "1" or "5", because a movie I did not like meant I just wasted 2 hours of my time. On the other hand, a movie I did like was an enjoyable and relaxing 2 hours.
So I rate everything to the polar ends, and also tend to have pretty varied choices for what movies I like. Usually the only genre I avoid is Horror/Psycho/Chainsaw Death films.
