Environmentally friendly animated film with a strong message that doesn't club anyone over the head--but it certainly can't be missed. Zak (voiced by Christian Slater) is a heavy-machine operator whose job is to push over any vegetation in his path. He's shrunken to wee size, however, when Crysta (Samantha Mathis), a fairy of the forest, not only finds him cute but wants him to see the results of his handiwork. They end up battling Hexxus, an evil force imprisoned in a tree, which now wants to destroy all of Ferngully. Robin Williams offers genuine comic relief as a bat named Batty Koda. Agreeable without making much impact, it's a piffle of a film for one that deals with such strong subject matter. --Keith Simanton
