'Melancholia'

We get that Kirsten Dunst's bride is depressed, and the world's also about to end, but why on earth would she skip having sex with smoking hot new hubby Alexander Skarsgard and instead seduce a wedding guest for a meaningless quickie? At least no one's genitals were mutilated. (See, or rather don't see, Von Trier's 'Antichrist.')
