Shabba-Doo is always worth watching. Though he doesn't dance much in this one, the filmmakers seem to have been surer of the appeal of their dance numbers than of their plot, and in a way that's a self-fulfilling philosophy. The choreography (mostly a succession of babes doing angular urban moves) was interesting enough, but the asymmetrical plot-- which ostensibly follows a pair of cops, one stable and the other neurotic, but is dominated by the charismatic Shabba-Doo as a less crucial character-- eventually falls apart in a race to wind itself up in the time left over after all the dancing.
