GET OUT tied together social facts (e.g. that African American missing-persons cases receive much less attention from the media and law enforcement), anxieties and fears (e.g. that African Americans will always only be seen as bodies to be used) to craft one of the best thrillers I've seen. US, on the other hand, is seriously underconceived. While the horror sequences are expertly staged, the Tethered are badly conceived. If the Tethered are an experiment, then who is doing the experiment? How are people tethered? How on earth does Lupita Nyong'o's character forget having been in the underground? What could have been a fascinating allegory for class resentment instead falls into a series of logical flaws that are irritating coming from a director whose previous film was so rich.
