Both for me. I love the idea of all these properties I'm not familar, or overly familar, with, getting explored and put out there, with Marvel, be it Inhumans, or not.
Or, my Uncle having his favourite childhood superhero, Doctor Strange, getting a live-action, feature-length, theatrical release, Cumberbatch or not - just go ahead and do it, Marvel!
Then, I love that, even if it's a shame that Wonder Woman hasn't got a film since 2009, a live action film at all, at least it's a big comic book character, or pop culture icon, getting interpreted again, in a fresh, exciting way. Or, for the first time, to some extent.
Then, all these other, non Superman or Batman heroes getting films? Yeeeessss. Excited as Spider-Man swinging through New York.
I wish there was a both option, but I'm a bit more excited for a Justice League film that another Avengers film, though I sort of prefer Avengers generally, and LOVE Ultron, whereas they COULD theoretically go anywhere with the antagonist or villain in Parts One and Two of JL, which is brilliant, and terrifying, in a way.
