This is sci-fi, but it's sci-fi qua sci-fi European style, with a focus on aesthetics and a sparseness of dialogue--certainly not a "messy American sci-fi action movie."  This enables the viewer to picture and concentrate on the fascinating premise, which is that of a society in the not-so-distant future where your station in life is institutionally determined (and limited by) your genetic code.  Ethan Hawke works hard to defy genetic limitations and societal expectations and to impress Uma Thurman, who in turn doesn't say much but looks very smart and very pretty.
