In 1997, maybe the movie Gattaca could seem strange, or just Sci-Fi, or not real, but now, in the after-postmodern times, it seems more and more real.
In the beginning of the picture, the couple that wants to have a child in the “natural way” is featured as a kind of “old fashioned people”, dressed in a kind of “pre-2WWar way”, or in a “modern”, or yet “old modern” fashion.
So, we can see that Gattaca is pointing to what comes next to that “old fashioned couple”, it is pointing to a “postmodern dream”: control and efficiency.
But the “postmodern dream” came in the “after-postmodern times”, and so it comes with failure in control and efficiency.
Gattaca shows an “after-postmodern mythology”, in a Jungian sense where “mythology” is something deeper than the apparent reality. The Greek myth of Procrustes is represented in an opposite way: the main character make some kind of surgery to stretch his legs, instead of cut it. That main character is a symbol of someone that trespass time and space, he comes from modern, trespass postmodern and arrives at post-modern times achieving his own dream of freedom, despite the supposed control and efficiency of a world dominated by gene-owners, gene-rulers, gene-power.
