Data in itself is white noise. It's only useful if you know what to look for.

The almighty algorithm is a dumb tool, it can only do what is asked of it. If Netflix's executives do not understand which metric is meaningful, then it doesn't matter how many they have access to.

Netflix supposedly hangs big decisions on the early completion rate. I assert that's a completely wrongheaded approach that is burdening them with a growing library of very expensive dead weight nobody will ever watch again; and worse still, it's developing a reputation for that.
