Hip-hop and a simmering Mike Colter help 'Marvel's Luke Cage' put the human in 'superhuman'

It takes only about 90 seconds for "Marvel's Luke Cage," the latest Netflix series set in the Marvel Comics universe, to address the idea of what it means to be a hero in the black community. The drama opens at a barbershop in Harlem run by Pop (Frankie Faison), a kind of neighborhood patriarch. The lively conversation has turned to a sign on the wall listing the few highly accomplished, widely revered men -- Muhammad Ali, Nelson Mandela, Michael Jordan -- eligible for free haircuts at the establishment. Little do most of them know that Luke Cage (Mike Colter), the quietly intense guy sweeping up hair in the corner, has the potential to join this hallowed club (that is, if there were any hair on his head to cut). Thanks to a medical experiment gone awry, Luke has been gifted with superhuman strength and bulletproof skin but would rather fly under the radar than harness his powers for good.
