The powers: The standard flight-strength-speed combo
The actor: John Haymes Newton in season one, Gerard Christopher in seasons two through four
The run: 1988-1992
The villains: Lex Luthor, Bizarro, Mister Mxyzptlk, aliens, spies, etc.
The tone: All over the place: First cheap, then comic-book bright, then gritty, then canceled
Of note: This syndicated show was all over the map -- much of the cast was replaced after the first season, the setting morphed from college to the Bureau of Extra Normal Affairs, and the tone see-sawed back and forth. But none of these things killed the show -- it was finally taken out by legal action from Warner Bros., which went on to develop "Lois & Clark: The New Adventures of Superman."
