“Jojo Rabbit” is--at first glance--quite the peculiar film. It opens up with vintage footage of Nazi Germany; Hitler-hailing fascist nutjobs going wild in exaltation over their idol. All this while a German rendition of The Beetles’ “I Want to Hold Your Hand” plays...this is the part where you, the viewer, may start to scratch your head in bewilderment, then utter to yourself what I did during this sequence: What. The. Hell.
