* AlternateCharacterInterpretation:
** There is a {{serial killer}} living right under Superman's nose and he never even notices. [[{{Adorkable}} Jimmy Olsen]] may seem innocent at first glance, but by the end of the series he has a substantial body count going on. In pretty much every episode, Jimmy is professing his love for a girl and by the end of the episode he'll have won her over only for her to vanish without a trace in the next episode. Even [[PlotArmor plot armored]] characters aren't safe from him, Lois's sister goes from a central storyline to never heard from again! (To be fair, this could just mean he's a shit boyfriend who can't keep a girlfriend worth his life.)
** Tempus's description of the boring, pacifistic future (coupled with how easy it is for him to get loose ''because'' everyone's a pacifist) can make you wonder if the utopia Superman will usher in would be a good thing or not.
* ArcFatigue: From the first attempt at the wedding, to the actual wedding finally happening, takes ''eleven episodes''. While annoying on DVD, this must have been intolerable in 1996.
** It was, particularly since the first attempt at the wedding had been ''intended and promoted'' as the ''actual'' wedding. At the last minute the network insisted that they change it, for fear that people would stop watching after Clark and Lois finally tied the knot. Say "frog-eating clone" (or just "clone") to a [=FoLC=] (Friend of Lois & Clark) and watch what happens.
* BrokenBase: Particularly fans of ''[[Series/TheAdventuresOfSuperboy The Adventures of Superboy]]'' TV series, which was ''probably'' axed by Creator/WarnerBros to avert the possibility of [[DuelingShows two competing Superman shows]]. While nobody will claim that ''Superboy'' was a milestone of television, it left a bad taste in many fans' mouths which still persists today.
* BizarroEpisode: "Soul Mates", which involves Lois & Clark jumping between HollywoodHistory time periods. Each time, Clark is a heroic rogue with a mild-mannered alter-ego, while Lois is trapped in a ShotgunWedding by Tempus.
* CrossesTheLineTwice: ''Everything'' about Tempus's bid for President, from naming himself John Doe to mind-controlling everyone with a phone, declaring war on the Amish who don't have phones, shoving a bodyguard out a window while proclaiming that even Reagan couldn't get away with this, and naming a convicted criminal who killed his parents at age 3 Secretary of State.
* DoNotDoThisCoolThing: In the DVD commentary on the Episode "Season's Greedings", writer and actor Dean Cain said that it was really fun for him and the rest of the cast to act like greedy children. The message he intended to send is that it is a bad thing to be greedy (or at least a bad thing to be very greedy). It did look very fun being greedy, and the character did not suffer any penalty for greed because their greed was a result of the Toy Man's evil toys. So the overall plot has the characters having fun by being assholes, ''and'' getting away with it because they have an excuse. The episode was entertaining.
* EnsembleDarkhorse: Tempus is a fan-favorite villain.
* FanficFuel: Mindy Church was never caught onscreen; many fanfics have her receive comeuppance in some way, whether it happens between Seasons 3 and 4 or in stories beyond Season 4.
** What became of Cat Grant.
* HelloAttorney: Mayson Drake (Season 2) and Angela Winters ("The People Vs. Lois Lane").
* HilariousInHindsight:
** In "The Night Before Mxymas", Mr. Mxyzptlk (Howie Mandell) asks Superman, "So, are we ready to [[Series/DealOrNoDeal make a deal]]?"
** In "Resurrection", Lois and Clark disguise themselves as greasers in order to sneak into a prison visitor's area. Their aliases? [[Series/BuffyTheVampireSlayer Angel and Spike]].
** Fred Willard makes guest appearances as a U.S. Presidential candidate. We all know how well ''[[WesternAnimation/WallE that]]'' went...
** In "Don't Tug On Superman's Cape," Lois has an ImagineSpot where Clark acts like Film/JamesBond and she's stuck in the role of a Bond Girl. Teri Hatcher would actually go on to [[Film/TomorrowNeverDies play one not long after the show ended.]]
** The Final Episode aired on June 14, 1997, the same month and day that [[Film/ManOfSteel another Superman adaptation]] would come out 16 years later.
* MagnificentBastard: Lex Luthor.
* OneSceneWonder: The government agent from "Double Jeopardy".
* RetroactiveRecognition:
** John Shea is probably best known as Lex and playing Adam on ''Series/MutantX''. It's nice that he's still working in his 60's, but damn...Talk about slumming it as an actor.
** Jimmy Olsen is [[Film/FinalDestination being stalked by death]] every moment of his life ...Not unlike this show, come to think of it.
** As for the other Jimmy? He once saved the world from [[Film/DungeonsAndDragons Jeremy Irons' eyebrows]].
** After leaving the Daily Planet, Cat Grant parlayed her years of gossip column experience into [[Series/BabylonFive commanding a space station]].
** Inspector Henderson is initially played by Brent Jennings, better-known as JiveTurkey vampire [[Series/BuffyTheVampireSlayer Mr. Trick]] (Jennings reprises the role of Henderson in ''[[WesternAnimation/SupermanTheAnimatedSeries Superman: The Animated Series]]'').
** Ching (that is, the [[TheOtherDarrin first one]]) ended up marrying an Earth woman named [[Series/TheCloser Brenda]].
** [[Series/CSIMiami Det. Calleigh]] moonlights as Lana Lang for an episode.
** On that note: Hey, [[Series/{{CSI}} Warrick]], nice dreadlocks!
** In Season 2's ChristmasEpisode, Jimmy Olsen's girl of the week is (fittingly) [[Film/TheWorldIsNotEnough Dr. Christmas Jones]].
** And he follows it up with dating ''Film/{{Bloodrayne}}.'' Seriously, what is it with Jimmy and these women?
** Raymond's brother [[Series/EverybodyLovesRaymond Robert]] used to be an [[CannotTellAJoke unfunny]] clergyman named "Reverend Bob".
** [[Series/{{Supernatural}} Bobby Singer]] once stole a scientists' invisible suits (maybe he needs them to help with demon hunting?)
* SeasonalRot: The fourth and last season is generally considered as weak due to the aforementioned ArcFatigue and DenserAndWackier plots.
* [[StrawmanHasAPoint Strawwoman Has A Point]]: The D.A. Mayson Drake dislikes Superman but is in love with [[LovesMyAlterEgo Clark Kent]]. In her first appearance Superman asks her why she dislikes him and gives several legitimate reasons for a ''clean'' official to dislike him:
-->'''Mayson Drake''' (''to Superman''): "Do you have a license to chase criminals? Do you read them their rights? If you injure someone are you insured?"
** She also discusses how Clark is standing up for the law despite the inherent risks, and says how she'd like to see Superman do that without his powers. To her, Superman isn't a real hero because he's not human, or at least is not with [[ThePowerOfLove all]] human weaknesses.
** [[spoiler:Sadly, the last thing she learns is they're the same person.]]
* TheWoobie: Alternate!Clark, who's bullied by Lana Lang, never became Superman, and had his Lois disappear.
