Add a "top friend" or flag of some sort to highlight those friends whose ratings you trust
We follow people for different reasons: similar tastes or interesting reviews, etc. We come to know that when friend X rates a film 4 stars odds are we will too. I would like the ability to flag them as "trusted" or something so that when I look at the "Also watched by # of friends" the ratings of those trusted friends show up first (or are flagged). This would allow me to follow more people than I do while maintaining a personal recommendation system.
