1-5 star rating system works out when you have a lot of data; and don't work out at all when you have poor ones.

Now, that rating only makes sense given the clustered group of people with similar taste. It's also adds complexity of the clustering said group.

Furthermore, I think people generally are not always the best critic. I totally can picture people being precise in their rating getting the most of the the recommendation engine, and the sloppy getting poor recommendations.

In that case, I can't blame Netflix for wanting to trim down the complexity for making it easier for the audience and themselves.

I don't care about the sloppy ones. All I care about is how well it was working for me.
