I have a peculiar fondness for bad movies of this era. This is less credible than "Flash Gordon Conquers the Universe." Lionel Atwill is a lesser villain than Charles Middleton's "Ming of Mongo." Still audiences thrilled to Himalayan avalanches and other exotic locales. If you want authentic high adventure, this is not for you. If you want to be a pre-teen waiting for "Destry Rides Again" to come on the screen while you're wolfing down a 10¢ box of popcorn, you'll love it. Hokeyness personified.
