3. The Confessions of Thomas Quick
This chilling documentary takes us through the evolution of one of Sweden’s most feared killers of all time—everything from his deep psychiatric troubles to his numerous horrific crimes. I love how they mix real footage and pictures in with well-executed re-enactments along with confessions and interviews from Quick, himself. Well-deserved 3.1/5 rating and 6.2 out of 10 on IMDb and by far one of the best serial killer documentaries on Netflix streaming in 2018!
