The title makes modern viewers think of waves of Romero-esque flesh-eating zombies--that's not what it meant then and, in any case, the title was probably thought up by some exec on the spot. Judge it for what it is (rather than what you thought/hoped it would be) and you get a pretty nifty, if creaky, 30s feature about the potential of an invincible army. It has none of the innovation of White Zombie. It feels very like a serial made into a movie. But it's not horrible, and it actually has some very good ideas.
