Michelle Erica Green of "Trek Today" writes that the story is "an entertaining and engaging episode about power, loyalty and the struggle between physical and mental pleasures... and because there's an alien in his body, Spock spends a lot of time smiling". Of the characterizations, she adds, "Nimoy appears to be having a wonderful time playing a relaxed, calculating villain, and Shatner portrays Sargon in an amplified booming benevolent voice that makes a nifty contrast to his would-be-Kennedyesque speechifying, expounding on the values that sent humans to the stars".
