Goodnight Mummy is tough to call: It sets up the movie perfectly, builds tension very early on and is likewise tightly shot, with the twin brothers performing strong. Yet the film's second act lets it down. There are scenes that stretch so long, when ending does eventually hit, you would think it happened in an instant. This is a hard movie to sit through ultimately and it is a shame because it has so much potential.
