Aliens from another world send a huge robotic accumulator to invade the Earth and absorb all energy it comes in contact with.
Imaginative, but basically mediocre sci-fi invasion drama is marred by wooden performances, outdated special effects, silly science and even sillier conclusion.
Maltin**1/2: "Diverting science-fiction with unique monster...Occasionally shaky special effects are compensated for by nice touch of mysterioso and convincing performances, especially by Emery as the alien's catspaw."
