Logic is in short supply. Burned-out cities have electricity, for example. My favorite: A hangar full of jets, buried under 1,000 years of dust, not only fire up instantly but still have full tanks of gas.
Here is a picture that will be hailed without controversy as the worst of its kind ever made. It could be renamed Ed Wood's Planet of the Apes if that title didn't promise more cheesy fun than the movie actually delivers.
If you're the kind of sci-fi fanatic who has to see every new futuristic action movie no matter how crummy it is then of course you'll check out Battlefield Earth regardless of how many cheap jokes critics crack at its expense.
Battlefield Earth is just a lumbering, poorly photographed piece of derivative sci-fi drivel, full of grunting extras scampering around in animal pelts and more dank, trash-strewn sets than I ever care to see again.
