I would love to see Marvel Studios put a huge focus on the Inhumans. With the movie rights to the X-Men belonging to Fox, I think Marvel could really evolve the Inhumans to what made the X-Men so appealing. Outcasts and weirdos with great power...with an added twist of genetically superior and pretty much the inheritors of Earth.
I think with the Inhumans, they actually have access to a type of storytelling that has not been done with any of the Marvel characters. That of operatic storytelling.
