I am perplexed. I am a longtime Netflix user and fan. By their count, I have watched and rated (their five-star scale) 1227 films over the last 10 (or so) years. They have 20 suggested movies for me as of this AM, including Being Elmo. It's probably a fine film but I looked at the trailer and decided to pass.
1227 data points, 76,897 micro-genres and 20 suggestions that I will pass on. Is this The Big Data we fear? There may be some big Type I and Type II errors.
