In this film, too, there is a battle between good and evil over the human race, represented by a woman, or more accurately here a madonna and child. The plot is complicated, but in the future there is a war between humans and machines. One machine is sent back from the future, by the leader of the humans, to protect the woman and her child against the much more sophisticated machine that wants to destroy them. As in A Stranger Came Ashore , where there is a line between earth and sea around which the battle rages, in Terminator 2 there is also a line, or more a fabric between times, the past and the future, into and out of which these machines constantly emerge to do battle. But perhaps the greatest similarity is in the ability of the bad machine to change shapes at will, which we see on the screen in incredible realism.
All fantasy is rooted in folklore, and all folklore is rooted in fact.
The Bodach delays the flooding of the glen and the drowning of the stones by calling up his Co-Walker, a copy or echo of himself, a projection of his mind, to lead the dam builders on a chase, since they cannot flood the glen until everyone is safely removed from it. He is finally destroyed at the end after his mimetic form is frozen into a statue, a stone that can be shattered, and careens into a pit of liquid steel. There are so many of these parallels between modern science fiction films and the Celtic folklore incorporated into Mollie Hunter's novels. And the way in which a callous and arrogant human is captured by the Sidhe, the dark and terrible but also pitiable Fairy Folk, in another of Hunter's novels, The Haunted Mountain , is reenacted in a film such as Poltergeist , where callous builders who put their subdivision over an old burial ground and thus unleash the angry but also very sad spirits of those who were buried there cause the imprisonment of the young daughter of an employee by these spirits. In both, it is only the bright love of the family that can recapture these prisoners of dark forces.
