I believe this series is about Addiction- an addict's life is a loop of scoring, using, withdrawal, scoring. There are two main character's but they are but one for the true personality of a messy addict is the control freak. Natasha Lyonne certainly offers a new perspective on the "heroine"- she's tough but heartbreaking. The humourous, almost slapstick beginning draws you into an existential nightmare. Russian Doll is not a cakewalk but it's worth the journey.
