@fastestblender: Have you been to other message boards? People doing the complaining don't read comics and 9 times out of 10 there only exposure to this media is the Marvel movies.
People hate because it is fun to do so.
You can't actually please these people they have chosen their side and will stick to it to the end. When DC do actually change their ways a more diverse set of books , a lighter tone with their shows with Flash and Supergirl people still complain.
It's just an echo chamber at this point full of teenagers on twitter with nothing better to do.
