Writer/director Jennifer Kent’s The Babadook (B) is a highly suspenseful Australian-Canadian psychological horror film focused on Essie Davis in a terrific performance as a grieving single mom and superb child actor Noah Wiseman as her disturbed boy. When they discover a children’s book about a maniacal madman who is trying to infiltrate their home, the mother and son must summon all in their power to preserve whatever sanity is left in their domestic life. Music and sound effects augment this classic tale of home and hero possession, and it almost fully delivers on the promise of its premise. It’s creepy, deeply relatable and a great example of how time-honored horror tools and solid acting can pack a paranoid punch.
