!The Comic Book

* NightmareFuel: The time-erasing void.
* TearJerker: ComicBook/GreenArrow apparently killing his best friend, Hal Jordan. ([[UnexplainedRecovery He got better]].)
* TheyWastedAPerfectlyGoodPlot: DC could have used the series as a way to restore [[ComicBook/{{Hawkman}} Katar and Shayera]]'s Silver Age history and undo most of the character's ComicBook/PostCrisis DorkAge stories. Needless to say, there's a good reason Hawkman's the image for ContinuitySnarl--and this is partly why.

!The Television Series

* CriticalResearchFailure: The old clockmaker mentions three apostles by name: Peter, Bartholomew, and... Luke? (A double failure because two other named gospels, Matthew and John, would have been correct choices.)
* SpiritualAdaptation: Of ''Literature/TheDaVinciCode.''

!The 1957 Film
* SeinfeldIsUnfunny: Or, rather, ''Zero Hour!'' '''is''' funny; it has been noted that, what with ''Film/{{Airplane}}'' and all, it's very nearly impossible to watch ''Zero Hour!'' with a straight face anymore.
** It's also not as overly melodramatic (and therefore not as silly) as some other {{Disaster Movie}}s might be, but it gets lumped right in with them anyway. Case in point: Warner Home Video marketed the DVD as part of their "Cult Camp Classic" line of films.
