The question of who killed Meredith Kercher, a British student living in Perugia, Italy, in 2007, was seemingly answered, if not right away, then in due time.

American student Amanda Knox, one of Kercher's roommates, was convicted of the murder—as were the Italian man Knox had been dating at the time, Raffaele Sollecito, and Rudy Guede, a man originally from Ivory Coast who Kercher had met at their neighbors' place downstairs.

But their arrests and that trio of guilty verdicts was only the beginning—and it's doubtful that Amanda Knox, a new documentary that started streaming on Netflix Friday, will be the end.

"There are those who believe in my innocence and those who believe in my guilt. There is no in-between," Knox says in a voiceover during the film. "If I'm guilty, I'm the ultimate figure to fear, because I'm not the obvious one. But, on the other hand, if I'm innocent, it means that everyone is vulnerable, and that is everyone's nightmare. Either I'm a psychopath in sheep's clothing, or I am you."

That's quite the choice she's laying out for us.
