Although it has little in common with the horror movies and apocalyptic fantasies reviewed here, Ferngully: The Last Rainforest won me over with its themes of humans losing touch with nature and becoming greedy narcissistic dorks who then cause the destruction of rain forests.
Warning: this movie is about 1 hour 15 min long and is children’s animated film, thus can be forgiven its heavy-handed approach since we all know that movies for children are basically propaganda from well-meaning but usually delusional dipsomaniac adults. The soundtrack has traditional Slavic folk music that sounds mystical and yet upbeat like Dead Can Dance, and this redeems much of the loss of atmosphere that occurs once any story transitions to cartoon.
The story involves loggers using a leviathan of a machine to chop down trees in the last rainforest and polluting the land. A human gets accidentally shrunk by the forest spirit (faeries in this case) and sees the reality of the situation and makes attempts to stop this. Meanwhile, the leviathan machine causes the emergence of a physical/metaphysical antagonist who is contra nature/the forest. He was trapped in the trees in a long-past age but the churning of the machine inadvertently releases him and he melds with the machine and takes control of it. His intent is to finish his diabolical plot to destroy all forests and the life within them, possibly branching out Antaeus-style to destroy all life after that.
Naturally, our heroic characters launch on a quest in situ to defeat this monster. The intro mentions the pre-history: the humans also used to know of the existence of the fairies and during the black-demon cataclysm a Satan figure called Hexxus was spawned whose goal is to destroy the forest, and while the humans ran away, the fairies trapped Hexxus inside a tree. As you can imagine, a restoration of the magic in the soul brings back the fairies and possibly saves the last rainforest.
You probably do not want to watch this as an adult unless you are so drunk that you have an irrepressible urge to destroy rainforests and need a simple, step-by-step guide to changing your attitude. I mostly recommend this for adults to show to children, who are never too young to be taught the right propaganda — and I think this is probably better than the other options — to program them for zombie-like life among the office towers, fast food joints, sewage treatment plants and arms dumps of the modern world.
