Great review from Roger Ebert. Here’s a wee bit:
What is genetic engineering, after all, but preemptive plastic surgery? Make the child perfect in the test tube, and save money later. Throw in perfect health, a high IQ and a long life-span, and you have the brave new world of “Gattaca,” in which the bioformed have inherited the earth, and babies who are born naturally get to be menial labourers.
This is one of the smartest and most provocative of science fiction films, a thriller with ideas. Its hero is a man who challenges the system. Vincent (Ethan Hawke) was born in the old-fashioned way, and his genetic tests show he has bad eyesight, heart problems and a life expectancy of about 30 years. He is an “In-Valid,” and works as a cleaner in a space centre.
