Great concept. This used to be my favorite feature in Netflix (they gave really on-point recommendations), but they have since done away with the feature assumingly because they want to promote their streaming service (and divert attention from the 90%+ movies not offered on streaming). What would it take to make your results better? (lack of data, algorithms, other?). I was searching for something just like Movielens, the problem is that your results for recommendations aren't so great.
