A glacier attacks.
Epic fantasy. The flaws are not subtle: Consistently pornographic portrayals of women, weak characterization, weak environments (because the rotoscoped actors have nothing to work with), terribly uninspired worldbuilding. The whole idea of an army mustering to defend a country against a glacier is great kitsch, as dumb as “The Coming of the White Worm” (1933/1941/1989) and dumber than The Adventures of Hols, Prince of the Sun (1968). Still, relatively realistically proportioned Ralph Bakshi feature fantasy animation is worth seeing even with the sensibility of a contemporary crappy game of second-edition D&D.
