MCU fans’ mindset
The MCU isn’t just a collection of movies. It’s a mindset. People who watch and re-watch MCU films over and over again have come to have action scenes play out in their heads at random moments in life. For instance, non-MCU guys would just see two cats fighting in the top picture.
But for MCU fans, it’s actually a showdown between two powerful figures who aren’t above using weapons of mass destruction to put an end to their foe. All that clawing and biting will build up to a marvelous action scene involving two highly trained killers having an epic battle to the death.
