I don't think using 2 minutes is a very sensible metric for counting whether a movie (or TV show has been watched). The auto start feature which is irritating as hell means that when you click on a movie to read what it is about means that it starts playing. If you are dealing with the kids or getting dinner ready the movie will be playing. In addition there are several movies in netflix that I thought I would give a go, but they weren't very interesting so I stopped watching. Perhaps Netflix still considers a disinterested audience an audience. Watching 70% of the movie I think would be a far more accurate measure.
