All-Star Superman/YMMV

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.
 * 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.
 * Rescued From the Scrappy Heap: 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.
 * So Cool Its Awesome

For the film:

 * Angst? What Angst?: Superman, upon learning that he's dying, merely proceeds to quietly put his affairs in order.
 * 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.
 * Nightmare Fuel: Parasite is this, in spades.
