In times of economic peril/uncertainty you need people there for you. This is the kind of sentiment that only works in a movie, real life is far more complicated than pat cliches. The performances are quite good, the biting satire does gets drowned out by sap (why?), and the song choices tend to lead audiences emotions (transparently manipulative)
"Intimate, heartfelt, and heartbreaking, Up in the Air is a worthwhile experience that features great performances from Clooney, Fermiga, and Kendrick and a timely message that resonates. It may not be the most engaging film, however it is enjoyable and well-crafted".
