Review: Award-winning horror ‘Nanny’ is quietly disquieting 

LONDON: Learning that “Nanny” is the first horror film to win the Grand Jury Prize at Sundance earlier this year might lead some to assume they’re in for something of a screamfest — but this is a far more subtle movie than that. Helmed by Nikyatu Jusu, “Nanny” is a quietly disconcerting thriller on Amazon Prime Video, full of slow-build tension and sinister insinuation — this is no blood-and-guts bonanza.
