Saw I-Robot this evening, what a cool film. It presented the usual philosophical sci-fi questions, questions such as, “What is life?” “What is the soul?” “What is free will?”, but also came up with some interesting unusual questions such as, “Are humans fit to exercise dominion over creation, including themselves?”
It certainly had enough to keep the intellect busy and combined with faultless special effects this film is one of the best this year. Well worth seeing.
Oh, and in case you were wondering, the three laws of robotics, according to Isaac Asimov, are:

1. A robot may not harm a human or, by inaction, allow a human being to come to harm
2. A robot must obey orders given it by human beings except where such orders would conflict with the first law
3. A robot must protect its own existence as long as such protection does not conflict with the first or second law
