It's an enjoyable monster flick. There's no denying the social commentary on the proliferation of nuclear weapons, a common theme among monster movies of its time (i.e. Godzilla, et al). However, it seems to have taken a lot of its story and style from The Beast from 20,000 Fathoms.
The special effects - specifically the stop-motion animation - are brilliant at times, and then suddenly lackluster, which was unusual for animator Willis O'Brien, a master of the craft.
Still, it's worth watching.
