Russian Doll: parents' guide

The heroine dies again and again: hit by a cab, tumbling down stairs, drowning, in elevator accidents, often suddenly and with bloodied faces; one leaves blood streaming from her eyes and nose. Alan dies repeatedly too. Season 2 adds shoving, threats and a robbery.

Constant strong language: one review counted about 30 f-words in the first episode and roughly 50 in the season 2 opener, plus s-words, pussy, prick, dick and crude gestures.

Frank talk about oral, anal and group sex; implied off-screen sex; groping; a man Nadia has just met slips his hand down her pants at the party. Brief bare breasts, including a topless dancer in season 2; a man wears a strap-on, nothing explicit shown.

Nadia smokes two packs a day and drinks constantly. Partygoers smoke a joint said to be laced with cocaine that turns out to hold ketamine. In season 2 a pregnant woman is fed cocaine, amphetamines and quaaludes; a dealer recurs.

Repeated deaths, rotting fruit and people vanishing from the loop build creeping dread in season 1. Flashbacks to Nadia's childhood with a mentally ill mother are painful, a beloved mother figure dies in season 2, and Nazi-era theft in 1944 Budapest is revisited.
