A great, understated, low-key film that is intelligent and philosophical.  The filming is beautiful, austere without being cold, and nicely uncluttered.  Ethan Hawke turns in a nice performance as a normal man battling his natural genes and the society that rejects him because of them.  He has an easy chemistry with both his co-stars, Uma Thurman, who is perfectly believable and looks convincingly like a genetically engineered human, and Jude Law, turning in an effectively heart-breaking performance, and a spoilt, genetically perfect man, who nonetheless cannot live up to his potential.
