Only You” gives us two people who should fall in love and live happily together for the rest of their days. They know it, we know it, and all of their friends know it. We also know with a confidence bordering on certainty that they will fall in love. And so there is a special kind of movie pleasure in watching them pigheadedly postpone their bliss - especially when they do it on Italian locations lovingly photographed by Sven Nykvist.
