Memento: parents' guide

Opens with a man shot in the head in bloody detail. Leonard punches a woman in the face, hits a man with a bottle and strangles another to death. Sexual violence: flashbacks show his wife attacked, bruised and choking in a shower curtain; the rape is not shown.

Heavy. Movieguide counted 88 obscenities and two profanities, mostly f-words and s-words, with about a third packed into one heated scene. A harsh slur for women is also used.

No sex scenes. Leonard is often shirtless and his bare backside is seen briefly. He hires an escort only to recreate a memory, and one scene hints at sex used as revenge, though nothing is shown.

Drug deals and a dealer's stolen cash drive much of the plot. A woman snorts what appears to be cocaine, and characters drink beer and smoke cigarettes.

Dark and tense rather than jump-scary. The out-of-order story keeps viewers uneasy, flashbacks to the wife's attack are upsetting, and a woman's death from an insulin overdose is shown. The ending is bleak.
