There’s a lot of talent on screen in Jamie Babbit’s dysfunctional farce about codependent sisters embroiled in a spiralling web of ill-considered coupling and accidental killing. Sadly, the cast can’t save Karey Dornetto’s script from the slough of wacky despond as sex addict Shannon (Judy Greer) drags long-suffering Martha (Natasha Lyonne) away from the would-be welcoming arms of fitness instructor Kelly (Aubrey Plaza) to help her dispose of an inconvenient stiff.

Naff jokes about rape, the Holocaust, and the wretchedness of Fresno leave laughter in short supply as the shrieky action pinballs self-consciously from barmitzvahs to pet cemeteries. Tonally, it’s not a million miles away from the aggravating screwball of Accidental Love, but at least director David O Russell disowned that recut catastrophe.
