"She dwells with Beauty – Beauty that must die" ("Ode to Melancholy"). John Keats was no slouch with words; Lars von Trier, on the other hand, is terrible and his latest ode to despondency is derailed by its clunky dialogue. But he inspires an unstintingly committed leading lady in Kirsten Dunst, compelling as Justine, the self-destructive bride who seems pleased that a giant planet is going to crash into Earth. Witnessing her poisonous parents (the impressive John Hurt and Charlotte Rampling) during the wedding speeches and you can see why. Melancholia is riddled with longueurs, the plot is absurd – but it's often visually arresting and the end is oddly moving.
