Glover is an actor of considerable presence, and here he lets us know his character is from hell, and hardly has to raise his voice. Around him, the family members begin to turn unhappy. A younger brother grows weak and without direction. The father is ill. The mother is morose over what is happening in her household.
Unwelcome visitors turn up to play cards and drink.
Eventually, like in every other horror movie, something must be done to destroy the monster. The movie seemed well-done but too long when I saw it January at the Sundance Film Festival. It has been trimmed, but still plays too slowly. What should be brooding comes across as too deliberate. The reality of Harry's invasion and its effect on the family still is being developed by Burnett after he has made its point.
