But the effectiveness of the theatrical proceedings evaporates once subsidiary characters, subsequent choreography and more pointedly dramatic musical passages enter the picture. As Prince Stone, a wide-eyed and eagerly ardent Robert Fairchild makes for a one-dimensional hero opposite Ms. Mearns's equally conventional portrayal of the heroine. Short-statured Christian Tworzyanski, who somewhat resembles Seth Meyers of "Saturday Night Live," could hardly look less regal as King Ocean. Dressed in Ms. McCartney's spare tunic, tights and booty-slippers, he might as well be the realm's mascot.
The "Terra" baddies, led by a blustery Amar Ramasar as their king, sport coxcomb hairstyles that repeat the sharp patterning on their body-coverings, which resemble tribal scarification or tattooing. Their sinister side mostly begins and ends there, as busy, repetitive athletic jumps and kicks (see any number of Mr. Martins's previous ballets) make them seem a roving band of cheerleaders.
