content: Well, a lot. More than a lot. Poor Will does his best with a doggie script. He accounts for the one star.I don't know why those enlightened movie companies insist in making one SF dog after another. Did you watch the "The Chronicles of Riddick", "Sky Captain", or "AvP"? There are plenty of others around, all of them sucking money out of our pockets.They need to fool us in order to pay for the great CGI effects I suppose. They fail to understand that if CGI is used to generate profits, it will kill the emotional content of the movie. What's left is the customary Hollywood Pablum dulling our senses.Do not relate this dog to any of Isaac Asimov's works. They stole the title and we shall punish them by forgetting this miserable mutt.
