Does anyone experience the Netflix recommendation system being useful? If you use their web browser experience then you can tell it to never show items again. But if you use mobile apps, Chromecast, Roku etc you do not get that option. My experience is that they keep recommending the same content over and over again, despite me already having watched some of it, and not wanting to watch the rest. It is also an incredibly user hostile experience: "here are the same items we showed you last time that you didn't want to watch, so you must look at them again". Heck they even go so far as recommending items where they accurately predict I'll give it low ratings, while ignoring the items where they accurately predict I'll give it higher ratings. I really don't understand why they do this. Is my experience unique?
