A lot of AI research follows these lines, and the state of the art in machine translation (which is NLP, therefore AI) for example, is a 100% statistical approach, with almost no expert knowledge or reasoning involved. And the crowds intelligence sub-field even has a fancy name, it’s collaborative filtering…
But you are right that expert-systems have lost their appeal as an AI tool, in favor of statistical approaches, and that leads to less reasoning possible over results.
Napoleon Dynamite – you’re right, he also mentioned that briefly. That probably is also why “Miss Congeniality” is the most rated movie in the dataset… :-)

That’s because this is not AI at all. This is just “crowds intelligence” software. I think what is really saddening you is the fact that after so many years of trying, AI approaches are still less successful than others.

Another curious anecdote related to the NetFlix challenge is the “Napoleon Dynamite” problem (http://www.nytimes.com/2008/11/23/magazine/23Netflix-t.html?pagewanted=all). Some movies are very “polarizing” and so, most NN approaches tend to struggle with them.
