Morgan is both of its time and points forward to the darker popular culture that would ensue later that year and into 1968, the year of international youth revolution. Indeed, its popularity among the young may well have facilitated this radicalization, certainly within Britain. The film's depiction of madness is deliberately ambivalent. The inner logic of Morgan’s statements and his sure self-knowledge, as well as his rejection of the consumer society’s superficial trappings, mark him as the only sane character. —Jon Savage, The Guardian
