John Simon noted that the novel's most ambitious effects were based on language and the alienating effect of the narrator's Nadsat slang, making it a poor choice for a film. Concurring with some of Kael's criticisms about the depiction of Alex's victims, Simon noted that the character of Mr. Alexander, who was young and likeable in the novel, was played by Patrick Magee, "a very quirky and middle-aged actor who specialises in being repellent". Simon comments further that "Kubrick over-directs the basically excessive Magee until his eyes erupt like missiles from their silos and his face turns every shade of a Technicolor sunset".
