In reply to Saor Alba:
Yet, interestingly, both Bullock and Fitzgerald are critical of, and seek to highlight, the quintessential emptiness inherent in the modern condition, the flawed spirit of consumption, the perpetual triumph of style over substance and the relation between self identity and mass culture society. Both hold a mirror up to the character of the society in which they write and, essentially, question what it is that makes us happy whilst, at the same time, questioning the very grounds upon which any claim to happiness might be made and, ultimately, whether it is attainable at all.
