The careers of Reginald and Warrington Hudlin took off with this exuberant teenage comedy, starring the rap duo Kid ’n Play (Christopher Reid and Christopher Martin). The loose, hectic plot includes rap battles, dance competitions, romantic rivalries and run-ins with the authorities — most notably the weary, hard-working dad played by the great Robin Harris. Pop’s favorite movie is the Blaxploitation classic “Dolemite,” a reference that is consistent with the film’s mix of rebellious mischief and respect for elders. — A.O. Scott
