“Amanda Knox” is a no killer in the strong game of tv ratings.

Despite Netflix’s trademark of not releasing ratings of its long list of tv shows, a media research firm did.

According to The Wrap, Symphony Advanced Media took advantage of its cell phone audio recognition technology, an extraordinary means of tracking what the viewers are watching with the use of their mobile phones.

The data revealed that “Amanda Knox” has produced a 0.3 rating in the adults 18-49 demographic and 382,000 followers since its debut on Sept. 30 in live-plus-five ratings. The results put the show behind Symphony’s numbers for “Making a Murderer” documentary which earned an impressive 0.8 rating and 1.1 million viewers.

Although interesting, the film is no less exhilarating considering it is a single episode whereas “Making a Murderer" presents multiple episodes that deal with any angle of the subjects.

The documentary lacks substance as it failed to explore Knox’s life and her challenges in the prison and how her relationship with her boyfriend of 5 days Raffaele Sollecito change over time.

Moreover, the short story did not show how Knox hired her legal counsel and what strategies did her lawyer apply to the case. Not even a credential or important profile of her attorney was revealed.

Lastly, it would have been better if Netflix included in their presentation the legal process in Italy. In this way, the audience will have a good understanding of the Italian jurisprudence.

These strong points if accounted in the show would have made it more appealing and pull a higher rating.

The new documentary of the streaming giant features a controversial case of a 20-year-old woman from Seattle studying in Italy, who was accused of killing her British flatmate along with two male companions. Knox and her boyfriend were twice convicted and twice acquitted for the murder of Meredith Kercher.
