The faith our filmmakers put in love is an amazing, flexible, all-encompassing faith. It's a faith they turn to when they hit a plot point they can't explain or a behavior that doesn't seem to fit the character. They use it to shoehorn songs that don't seem like they belong there, to justify all manners of joys and utterly inexplicable suffering, and even, when creativity fails them (which it does often - so capricious, no?), to create twists that can move along a story that seems utterly unwilling to move.
Such is their faith in love that "Pora Pove" was deemed a worthy story ....
