This one is absolutely "so bad, it's good". The characters are wooden, the dialog stiff, the plot contrived. All in all, it's one of the most entertaining films I have in my vast collection of classic sci-fi space movies. Sure, there isn't a whole lot of outer space in it, and few rockets...and way too many fist fights where nobody's hat falls off. But the leaps in logic, the never-ending stream of vehicles that the characters drive, the bad line deliveries...all worth the price you pay. On the truly plus side: it is beautifully photographed, and the editing is pretty tight. Personally, I can't wait till this one comes out in DVD. I consider this one better than the Commando Cody serials (1951, 1953), and I'm a big Cody fan. The only thing missing is Judd Holdren (Captain Video, Zombies from the Stratosphere, etc.). Delightful.
