Not sure if it was a good idea to reveal everything. It takes away some of the element of surprise that the after credits scenes would give.
I was never a big fan of the Inhumans or Doctor Strange (sorry!), either. They're part of the Illuminati, though. If there's going to be a Civil War, I guess it makes sense for them to have movies but I don't know. Then again, i never gave a second thought to the Guardians of the Galaxy and that turned out okay. Certainly going to be interesting times ahead. Good to see Marvel isn't being complacent.
