Critic Michael Brodhead argues that "Biggers's sympathetic treatment of the Charlie Chan novels convinces the reader that the author consciously and forthrightly spoke out for the Chinese – a people to be not only accepted but admired. Biggers's sympathetic treatment of the Chinese reflected and contributed to the greater acceptance of Chinese-Americans in the first third of twentieth century." S. T. Karnick writes in the "National Review" that Chan is "a brilliant detective with understandably limited facility in the English language powers of observation, logic, and personal rectitude and humility made him an exemplary, entirely honorable character." Ellery Queen called Biggers's characterization of Charlie Chan "a service to humanity and to inter-racial relations." Dave Kehr of "The New York Times" said Chan "might have been a stereotype, but he was a stereotype on the side of the angels." Keye Luke, an actor who played Chan's son in a number of films, agreed; when asked if he thought that the character was demeaning to the race, he responded, "Demeaning to the race? My God! You've got a "Chinese hero!"" and "[We were making the best damn murder mysteries in Hollywood."
