The mystery surrounding crime can be seen in literature through police novels, which had their advent with newspaper serials in the 19th century. Currently, narratives about real crimes are successful on screens. If finding the culprit with the purpose to restore order was the focus in the past, in contemporary criminal narratives the doubt about the guilt of the protagonists accused of murder is accentuated at the expense of the crime itself. In the present dissertation, we seek to identify the emotions stirred up by three original Netflix productions based on real cases of murder crimes: the documentary Amanda Knox (2016), the documentary series Making a Murderer (2015) and the series Alias Grace (2017). We start by pondering on Netflix s role as 21st century technology when producing content for its streaming platform and when sharing opinions and emotions on its social networks, therefore making a game of screens with the viewer/user. Both Netflix and contemporary criminal narratives have been guidelines for studies in the field of communication considering engagement with the public. Here, we intend to think about the criminal narrative in its origin in order to understand its variations in the stories unfolded by Netflix, and the emotions of the protagonists that can bring about judgment by creating the viewer s involvement with the drama. The question remains: do these emotions represent the anxieties of the current individual?
