It's better to keep small businesses like barbershops -- traditionally a cornerstone of African-American neighborhoods, a place to debate, joke, and gossip -- in the neighborhoods they serve rather than bringing in characterless chain stores that are found in malls all over the country. A major theme is integrity.
Riot scenes show police and rioters fighting with billyclubs and molotov cocktails on the streets of the South Side of Chicago in the wake of the assassination of Martin Luther King, Jr. A rioter nearly throws a molotov cocktail into the barber shop, almost killing two people inside.
Some kissing. Sexual innuendos on the order of "size isn't everything." A character is briefly shown in bed with a woman who was flirting with him earlier in the film.
Occasional profanity: "f--kin'," "s--t," "ass."
Ironic that a film about chain stores running small businesses out of their communities shows characters holding Dunkin' Donuts boxes.
