If you're looking for a piece of media to clear the confusing facts for you - this is not it.
The documentary is clearly very biased towards Amanda, making her the sole focus of the documentary and not the case - I am aware that it is titled after her name and therefore about her, but I feel the documentary unjustly shifted the focus of finding the truth from the case to a more "we're trying to prove she's innocent" film.
Would recommend to anyone looking for a good entertainment documentary, but in my opinion it does nothing but feed into the idea that Knox is innocent and absolves her of any involvement within the crime, feeding in to her dramatics.
