An oil tycoon (Michael Shannon), art curator (Tilda Swinton), and their son (George MacKay) are separated from the apocalyptic horrors outside, spending their time in a bunker writing books, arranging flowers, and eating lots of cake. But the facade steadily slips away after a young survivor (Moses Ingram) enters their home.

Filled with dark humor and even darker revelations, the film also happens to be an uplifting musical, but those two sides never gel in a satisfying way. Instead, it ends up feeling bloated and, even worse, doesn’t have memorable songs.
