What is Russian Doll season 2 about and what are the reviews saying about the Netflix show?

Trippy, time-travelling comedy Russian Doll returns to Netflix this week for a second season. It has been three years since the critically-acclaimed first season aired - so fans have waited a long time to see what happens next to droll New Yorker Nadia, played by the show’s co-creator Natasha Lyonne.

In season 1, Nadia is trapped in a time loop at her 36th birthday party. To her terror and irritation, she keeps on dying - only to reawaken, again and again, at the beginning of the party.

Eventually, she meets Alan - played by Charlie Barnett - who is himself stuck in a time loop. They realise they are linked by some quirk in the space-time continuum and must help each other to escape.

Season 2 picks up the action almost four years later - with Nadia’s 40th birthday approaching. But rather than stick with the premise of being stuck in just one day, the new season sends Nadia and Alan on journeys back in time - starting with the East Village in 1982.

Much of the season then concerns Nadia’s quest for a treasure stolen from her Hungarian Jewish ancestors in World War II. This harks back to the gold krugerrand she wears as a pendant in season 1, which viewers learn is the last of 150 that her Holocaust survivor grandparents bought as a nest egg to keep safe from the fascist regime.

Netflix’s synopsis reads: “Season two of Russian Doll will continue to explore existential thematics through an often humorous and sci-fi lens. Discovering a fate even worse than endless death, this season finds Nadia and Alan delving deeper into their pasts through an unexpected time portal located in one of Manhattan’s most notorious locations.
