Netflix's biggest problem is not the recommendation engine, but their lack of content. If they allowed you to filter out the junk you don't want to see and what you've already seen, there would be hardly anything left. They've been losing rights to stream left and right. That's why there's such a rush to produce their own content in other countries. Some of that is halfway decent, but there's a lot of formulaic, repetitive stuff.

And while saying that, I appreciate their high level technical staff. These decisions are made by bean counters.
