Operation Mincemeat is a victory for the underdog, in themes as well as in reality. Relatable characters with vibrant backgrounds, regardless of their size, go on a Frankensteinian journey to divert the Nazi battalion to Sardinia. From songs about wanting to be a maggot to heart-wrenching glimpses into tragic love stories, it’s as eclectic as it is entertaining. Rhythmic pop music, a contemporary musical theatre sound, the odd rap segue, and a tune that would feel at home at Berghain for good measure (“Das Übermensch”) are the foundation of this life-affirming, riotous history lesson.
