I stopped subscribing to Netflix. Their recommendation engine is honestly terrible. They'd be much better off using curated genres.
I would say that I am able to find something I want to watch on Netflix about one out of every five attempts. The other four end with me giving up in frustration after 20-30 minutes of looking.
I wouldn't pay even a single dime for the service, myself. My partner does, and every now and then I get bored enough to give it another shot. Usually I regret it.
They have a very positive view of their recommendations, like they have of their customized thumbnails.
Yet I, and all of my friends, find the recommendations nearly useless, and I also find the thumbnails mostly ugly.
