In the story, the central characters, three children, travel to another planet to rescue their father from the grips of evil.
Evil is portrayed as the loss of freedom of choice.
The evil character cajoles the children to surrender by pointing out the ease and peace of not having to make decisions, of not having to be responsible, of becoming robotically like everyone else. The children are urged to let IT slide into their minds and everything will be easier. I happened to see the exchange between Rosie O'Donnell and Tom Selleck about gun control. I, for one, am persuaded that this is a freedom I'm willing to relinquish. But it does illustrate how freedom and responsibility are inextricably linked.
