On the X-Men/Inhuman thing, I always felt it was variations of the same theme but different effect. X-Men being the outsider among us, the Inhumans being the alien among us and the Eternals the gods among us. Though generally I felt Inhumans were everything Mutants wanted. Their own culture as society that was away from humanity. If anything, Inhumans are more of a person from a foreign culture immigrating to the West and seeing them cope. That alien aspect of the Inhumans to me is what's cool.
