Because I watched The Girl with the Dragon Tattoo, I might also want to watch a documentary on Hannah Arendt?!
There is also a strange lack of "self-awareness" on the part of the recommendation software: one of the "top picks" for me is the show Luther. But I have already seen every episode.
Then, just two lines down the screen, a new set of selections is offered "Because you watched Luther." So here the software knows I watched Luther? Why didn't it know this just a moment before?
