This movie was loosely--and I do mean loosely--based on a Ray Bradbury short story of the same name. The Bradbury story was clever and thought-provoking. This movie had a great cast, from Ben Kingsley to Catherine McCormack. Too bad the script was terrible. It had cardboard characters (Kingsley plays a one-dimensional, evil capitalist; no other kind exists in movies these days) and pitifully executed action--the underwater scene where a man holds his breath for over 5 minutes and kills a giant moray eel with a knife to the gill, while avoiding the foot-long teeth and snapping jaws, had to be seen to be disbelieved. To add insult to injury, the science was so bad, it made The Core and Armegeddon seem scholarly--I still don't see how THAT could be possible. They even screwed up a drowning resuscitation scene so badly....never mind.Terrible. I wish I didn't waste the time on it.
