Scary Stephen King Adaptation 'The Boogeyman' Delivers Chills but Lacks Subtlety

The film is a loose adaptation of a Stephen King short story about a monster that preys on a grieving family.
The plot focuses on sisters dealing with their mother's death who encounter a haunted man bringing darkness.
The film is directed by Rob Savage, who directed the horror film "Host."
The monster in the film represents grief like the creature in "The Babadook."
While the film has scares and an unsettling monster, it lacks inventiveness and impact.
