There was a conversation about film where a sequel was described as The Empire Strikes Back of the series (It may have been Across the Spider-Verse, which is fair) which got me thinking about what movies could be readily understood taglines. If you were to say a franchise is getting its The Dark Knight, it suggests that a major villain will push the hero to his/ her limits. And that got me thinking about comic book stories so iconic that you could apply the premise to other heroes.
If you were to say a story is the franchise's version of the Dark Phoenix saga, we'd figure a hero in an ensemble gained immense power and became a bad guy. The franchise's version of the Night Gwen Stacy Died would be a tragic loss. A franchise's version of Born Again features a protagonist pushed to the limit.
What are the other stories so iconic you could apply the premise to something else?
