The undeniable narrative of superhero movies in 2023 was arguably the most disastrous on record since Marvel took off in 2008 with “Iron Man.” The “Marvel wobble” year, as it’s been called, saw Marvel’s first flop ever, “The Marvels” (their lowest-grossing film ever), a major box office disappointment, “Ant-Man And The Wasp: Quantumania,” and a series so poorly reviewed (“Secret Invasion”), the studio would love to pretend it didn’t exist.
