Mother’s Instinct could have been named ‘Mom gone bonkers’. Turning the concept/ idea/ theme of a mother’s selfless love for her child on its head, this 2024 thriller, now streaming on Prime Video, is a pulpy watch, with maternal instinct going into a zone dark enough to result in murder. A couple of them, in fact. Set in the 1960s and headlined by Hollywood A-listers Anne Hathaway and Jessica Chastain, the directorial debut of acclaimed French cinematographer Benoit Delhomme has a Hitchcockian feel of unease and foreshadowing, but never really lives up to its ultimately pulpy potential.
