Burglar Mammy was horrendous, a confirmation of every harsh judgment levied against Mad Men for being too much of a white upper-middle-class historical fantasy, a show that’s not willing or able to really go where it labors to convince us it’s going. If Burglar Mammy were a dream figure attached to a particular character, and if Mad Men had shown any inclination to go anywhere substantive with its allusions to civil rights and racial anxiety, and if it hadn’t given us a black Playboy bunny, a black prostitute, a black mugger, and other disreputable minor characters over the years, but no people of color with personal or even narrative substance, I might feel differently about her.
