John Carney’s Once (B+) is a treasure box of a musical with an unassuming storyline showcasing a man and a woman who enter each other’s lives when they need each other most. Glen Hansard and Markéta Irglova play the unnamed pair – he, a busking Irish guitarist and she, a Czech pianist, who find themselves “Falling Slowly” into the spell of making beautiful music together. Very much in the vein of Before Sunrise, the duo are fated to be together and bring out talents and insights in each other that they never could have found separately. In its simplicity and handheld look and feel, it celebrates the joy of discovery and the brilliant promises of second chances at love.
