Tim Lyons has delivered an extraordinary film with an enthralling narrative throughout. Noelle Clarke’s portrayal as Sister Mary is spellbinding, a highly captivating performance. Megan McArthur’s role as Sister Adana is equally commendable. A terrific cast delivery. Costume/production design is exceptional – as is the breath-taking location scenery (filmed in Northern Ireland). Cinematography (by James Taylor) is second-to-none, which aids the haunting tone and frightening ambience. Post-production, lighting and sound are of the upmost professional quality. A startling watch. Highly recommended.
