To briefly address Vision’s concerns, mentioned above…
In Anthony and Joe Russo’s 2016 film “Captain America: Civil War,” the thirteenth film in the MCU, Vision’s android character (Paul Bettany) argues – logically and sanely – that the characters Superhero animals should probably subject themselves to some sort of scrutiny in order to control their rogue power. Vision points out that, 13 films in the series, there are already dozens of superhuman characters on Earth, and the number seems to be growing. The MCU, back when it started in 2008, still takes place essentially in the real world. During the “Civil War”, the reality was rented. Comic fans naturally understand the ever-evolving lineup; had decades of comic history to recreate and draw from. But maybe this character should be a little more surprised that the world 5 years ago was still normal, not now.
This could be the MCU’s last attempt to connect itself to the real world. Attempts have been made to turn Thor into a cosmic alien rather than a legitimate god, and the Guardians of thje Galaxy are humorous sci-fi characters with no direct link to the gods. character on earth. The next film in the series, Scott Derrickson’s “Doctor Strange,” left any point of view that there was a scientific explanation for the MCU and explicitly stated that magic is real. Now “wizard magic” is a plot point, practically wiped out. Now, anything is possible and needs no explanation.
“Werewolf by Night” says that monsters are real, and there’s nothing shocking about it. Werewolves are a thing. The Swamp Beasts are friendly buddies who know how to run the French press. The MCU, as always, has turned the extraordinary into something ordinary.
