You know the main reason why DC > Marvel? (This bleeds into the comics as well).
Because in the Marvel universe the plot (Thor is the expection) ALWAYS takes place in New York City
Every single movie we see the same bullshyt ass shots of NYC,
The fukking cabbies
The empire state building
The same final stand in times square
Nyc in the Marvel universe should be the safest goddamn place in the multiverse with X-Men, Spider-man, Avengers calling that place home. It makes zero sense for street level heroes to exist.
In any form of Marvel media whenever the mention that the Earth is in danger/being invaded, they really mean New York is in trouble.
I haven't seen any of the trailers for Age of Ultron, but I'm going to take a very risky gambit though it may sound way out there and guess the final battle/scene is in New york.
DC on the other hand are more creative and created two cities Metropolis (although boring) and Gotham (enough said) where Superman and Batman respectively
OWN their cities and don't share with the other heroes.
Wanna know why?
Because DC actually has the audacity to not play it safe and give the other characters their own turf (OA/Sectors for the GL corps, Fawcett city for Captain Marvel)
When the DC earth is in danger, it actually means the earth is in danger, it does NOT mean the Scarecrow released Fear toxin in the financial district of Gotham.
The avengers are based in Nyc
JLA have a watchtower in space orbiting earth
Marvel is childish.
