Sorry, I don’t buy it Wonder Woman as the ‘highest-grossing superhero origin movie of all time.
Reason being, it neglect a little movie called Spider-Man: Homecoming.
Spider-Man isn’t an origin movie, you say?
That’s where we’ll have to differ (because it is).
This iteration of Spider-Man is first introduced in Captain America: Civil War so it technically isn’t his first appearance. Then again, Wonder Woman was first introduced in Batman v Superman: Dawn of Justice so it wasn’t her’s either.
But what people who say Spider-Man: Homecoming isn’t an origin story seem to be missing is that there have been THREE prior versions of the character relatively recently, which means to include it again would bore moviegoers (The Amazing Spider-Man retconned the origin, making Peter Parker’s parents spies–sort of–which was dumb, though you can at least understand why they did it).
So Marvel Studios took a different approach. They emphasized Spider-Man growing in the role, so in a sense it is an origin film in that Parker–despite wearing the costume–is not Spider-Man.
Instead he’s awkward, and truth be told, not terribly good at what he does (a fact the movie emphasizes more often than once).
In other words, Spider-Man: Homecoming is an origin story, just not a blatantly obvious one.
