I completely disagree with the review posted on this site about the film "A. I."
It did not have a "false ending" and it does a beautiful job exploring deep social issues, most of which are probably beyond the reviwer. Like many sci-fi films the technology is only symbolic of our mundane. David could very well be a boy with ADHD or a heart condition, he is a child that does not meet his parent's expectations and so his unconditional love is not returned, until mercifully at the end. John Williams' soundtrack, as well as Spielberg's script and direction is in no way sloppy and this idea of cool negativity has become very old. Furthermore, George Lucas has more to do with this film than Kubrick, I believe Spielberg only credited Kubrick out of friendship and so that his family would benefit from the revenue of the film. This film and its music are beautiful and anyone who cannot comprehend that is too busy sticking their nose in the air to enjoy the movie.
