Legend, part of a mid-'80s wave of heavy duty high fantasy films (Dragonslayer, Ladyhawke, Willow and to an extent Krull) is the only one to base its lead character, played by Tom Cruise no less, on the same source as a Jethro Tull song. If that isn't legitimacy I don't know what is. Backlit goblins, gleaming unicorns, a field rich in the most photogenic pollen you've ever seen are all delightful, but Tim Curry's red-faced Lord of Darkness scared the crap out of all of us when we were kids.
