What "contemporary" themes has the MCU embraced?I'm not saying your not going to have diversity or anything like that in the DC. It's just that DC seems very early 2000's or late 90's were the MCU seems to embrace contemporary themes more often. In away it sort continues the same old feeling I think were DC is a very old brand. The first issue of Superman was in 1939 and Marvel came out in the 60's. It's almost in their blood for DC to be old school and traditional were Marvel is more radical.
Marvel's history goes back to 1939 with the first appearances of The Human Torch and the Sub-Mariner in Marvel Mystery Comics #1.
Have you read any comics since the 80s? DC's Vertigo line pretty much blew what Marvel was doing out of the water. They also gave us The Dark Knight Returns,Sandman and Watchmen which pretty much changed the comics landscape forever. The recent Watchmen series on HBO and Titans and Doom Patrol on DC Universe blows most of Marvel's offering on the small and large screen away. All are much more "radical" than Marvel's output. Legion is about the only radical thing "Marvel" has done on TV and that was under the Fox banner.
