Young Clark Kent discovers the source of his superhuman powers and moves to Metropolis to fight evil. The film depicts Superman's origin, including his infancy as Kal-El of Krypton and his youthful years in the rural town of Smallville.
Christopher Reeve essays the title role and makes it his own, combining correctly chiseled features with a likable comic humanity, while the film itself nicely balances special effects with the romance of Superman and Lois Lane.
All this makes a highly entertaining, though undemanding mixture, of sci-fi, romance and comedy, which could hardly have come off at all at any lower artistic level, nor without such a happy choice for the central part as Christopher Reeve.
The film is best when it takes itself seriously, worst when it takes the easy way out in giggly camp -- as it does, finally and fatally, when Lex Luthor enters the action.
