The Inhuman thing is very much like the X-men, in Agents of Shield and in the comics. The Inhumans worked better as their own Royal family unit... but bringing them to the populations of earth, having them live among us is too similar to the X-men. It makes things on earth very muddy and complicated. It was already a little weird that the general population of the MU had to somehow differentiate between Super humans and mutants, now they have Inhumans too. It makes each less special.

You’re right–we’d better get rid of the mutants then.
KIDDING!
