I remember meeting someone at a networking event who believed they could win the competition and get > 90% accuracy.

I tried to explain that you can't read minds; you can't account for the fact that I'm going to watch a movie that I saw in a random internet post that I didn't know that I liked...

Which was my real beef with the contest: Computers can't read minds. They can't analyze the content of the movie and have the emotional experience that a person can.
