Which is meaningless. If people need supplemental reading to understand an experience then the experience has failed to communicate its story.
That’s part of their game though. Essentially they paywall huge chunks of story, because there is always another movie, D+ series, novel, or comic book to sell.
Case in point -
In the 1990s,
Star Wars: Shadows of the Empire was released as a massive multimedia event, including a comic book series, a novel, and a video game adaptation for PC and Nintendo 64.
Shadows was set in the years between
Empire Strikes Back and
Return of the Jedi, and directly connected to those two movies. However, because it was released over a decade after those movies, it wasn’t required viewing.
You could still watch ESB and RotJ without it, and wouldn’t miss anything.
Contrast that to what Disney is doing with Marvel.
You can’t just watch Endgame and then Dr. Strange in the Multiverse of Madness…you need to buy a Disney+ subscription and watch WandaVision to know what’s going on.
Why was Wong training Abomination as a cage fighter in the Shang Chi movie? You need to watch She-Hulk on D+ for that.
Whats the connection between Kamala Khan, Carol Danvers, and Monica Rambeau?
You better get to watching WandaVision and Ms. Marvel.
