Coming in at a good duration of 93 minutes, The Babadook is intelligent, dark and frightening. Claustrophobia and gut-wrenching stress are intruded upon by a well meaning(?) outside world of school staff, social workers and haughty housewives. There is enough ambiguity to keep the viewer guessing as to what is actually going on, and the hero of the story is most unlikely–though always close by.
