I had the chance to see Children of Men, and while I'm not quite sure I'd call it "This generation's Blade Runner", the movie is darn good. Just to be sure folks get it - this is not a science fiction film, not any more than 1984 or Brave New World. It is a rather chilling look at how quickly things can downhill when faced with an inescapable situation. Luckily we don't have to worry about losing our civil liberties over here. ;) Sly personal attack against our lovely President aside - I would strongly recommend this film.
On a side note - I also saw Lady in the Water. Now - I've always like Night's film, even The Village. Lady in the Water is horrible though. Almost "Highlander 2" horrible.
