What amazes me about much of the negative critical reaction to Batman v. Superman: Dawn of Justice is the notion that the script is appreciably dumber, and appreciably more weightless (narratively and visually), than any of the Avengers films (see, e.g., Vision, the pinnacle of comic book dumbness) - which ushered in this new formula for financial success in this genre: throw in as many superheroes as possible to fuel more action and compensate for the fact that none of the them are that interesting. That said, on a personal subjective note, at 6-8 years old (the period when I was actually reading comic books), I was interested in Batman, Superman, and Wonder Woman,* and I was wholly uninterested in Captain America, Hulk, or Thor.
(* In the interests of full disclosure, Linda Carter made me feel things that I should not have felt at that age.)
