|Leonard Maltin/Plot synopsis:
Screw the Superman legend, forget logic, and full speed ahead: that's the attitude of this flashy sequel, wherein three villains from Krypton, with powers just like Superman's, threaten the Earth--while Lois Lane and the Man of Steel fall in love. Full of great effects and entertainingly played, but lacking the sense of awe and wonder of the original film, adding cruelty and violence instead. Unreleased in U. S. until 1981. Panavision.
