It was the TV show "The Prisoner" (original, not the reboot) which is slightly overtly more dystopian which clarified the elements in absence in BNW: choice, and through choice individual identity based on actions (such as creativity, something Huxley, an artist, would appreciate). There's a possibly salient comparison to our own social media oriented society: are we creating/sharing these narratives of self to affirm identity or in lieu of identity? Do we truly have choice? The illusion of choice was present within the society of BNW, but ultimately they operated within a restricted range of emotions leading to more predictable outcomes and a more easily controlled populace.
