I tend to get into these sort of deep sci fi movies.  This movie has a smart screeplay and the acting is very good.  Im no Ethan Hawke fan i assure you, I usually loathe him in movies, but he is very good in this, as is Jude Law and Uma Thurman.  The movie is fiction of course, but it really makes you think about the future and the trajectory of genetics.  If you are into sci fi at all, then i cant imagine you not really getting into this movie, everyone i know that has seen it has raved about it.  Highly recommended.
