- Angst? What Angst?:
- Superman, upon learning that he's dying, merely proceeds to quietly put his affairs in order.
- The same applies to Lex concerning his imminent execution. Though in his case, it's very clear his escape was already planned.
For the comic:
- Alternative Character Interpretation: An Epileptic Tree-ish one about Leo Quintum has become an almost essential part of the story's mythos on the internet after being pitched in an article by Cole Moore Odell. If you've finished the story, check it out.
- Ensemble Darkhorse: Nastalathia Luthor, despite making only a few appearances.
- Epileptic Trees: Many believe Leo Quintum is Lex Luthor, having travelled backward in time from after the end of the series where he briefly copied Superman's powers and Went Sane From The Revelation.
- Hype Backlash: When the introduction to volume two contains a promise that chapter ten proves Superman is cooler than God, well, this sort of hype has lead some fans to hold the story to an unreasonable standard.
- Magnificent Bastard: Luthor as usual.
- Signature Scene: Superman saving the suicidal teen, a powerful moment often regarded as one of the greatest Superman moments of all time.
- Win Back the Crowd: In the sense that the story allowed Morrison to use some of the concepts from his aborted Superman 2000 pitch and bring back his DC One Million continuity.
For the film:
- Big Lipped Alligator Moment: Quite a few scenes in the middle, particularly the one with Samson, come absolutely out of left field, have no relevance to the plot, and are never mentioned again. While comic readers know they're whole stories from the comic, they are very poorly implemented into the movie.
- Harsher in Hindsight: As mentioned on the main page, writer Dwayne McDuffie died suddenly of complications from emergency heart surgery the day before the film was released on DVD. Made all the more poignant because the film concerns Superman facing his mortality, and he had been giving interviews about the film mere days before.
- They Changed It, Now It Sucks: The film changes Solaris' fate from being captured and reprogrammed to being executed by Superman. It also changes the pacing of the prison riot so that Clark fails to save some convicts from the Parasite. The adaptation also cuts two of the comic's most affecting moments; where Superman gets to say a final goodbye to his father, and the famous scene with the attempted suicide.
