Marvel are the best, They have taken their time and DC think by throwing characters together as soon as they get moving will make the films gross a billion.

Batman v Superman has been in production for 3 years man!!! That's quite the opposite of rushing. And awful casting is your opinion.

With that said I agree Marvel is owning! But DC just got started so... Yeah.

And why can't 2 superheroes develop character at the same time again? Watchmen and Guardians of the Galaxy did well in that department. You're thinking too much into the idea of "marvel formula". See how BW came out in IM2? Or Hawkeye in Thor? Or Falcon or Warmachine or in Cap 2 in Im2? And how IM is set to appear in Cap3? Sometimes these characters bump into each other on other occasions other than the 1 Avengers movie every 3-4 years. It's why the MCU is so well received it isn't just a "cool concept" but the way other characters can react to a different heroes movie or even appear there makes the universe feel alive.

Just because it's a cool concept... I don't even know what to say to that.
