great analogy as i saw the movie once a very long time ago and had the same impression........ come to think of it i was watching dr who one time high on acid and the doc was trying to communicate a mutual understanding with some force of intelligence in a dome bubble. the bubble guy wasnt having it and was spurting plasma or whatever the hek it was inside the bubble in protest against the terms or something and i remember saying, look the bubble guy is having conniptions!!! and couldnt stop laughing over it, then the wife came home with 5lbs of u-peels and a loaf of garlic bread and another saga started lol!!!
