A dour almost-thriller about an air-traffic controller (Scoot McNairy) who inadvertently kills 271 people, including the wife and pregnant daughter of Ukrainian construction worker Roman Melnyk (Arnold Schwarzenegger), this is a trick of a movie that pretends it will subvert expectations by putting Arnie in a cuddly sweater. Helped along by a gloomy, oppressive score, it neither thoughtfully examines themes of trauma, guilt and grief nor moves with any sort of haste to its eventual, obvious, revenge-thriller conclusion, despite its short 90-minute running time.
