Got this from another site:
"The current Inhuman comic series deals with the aftermath of a mass amount of Terrigen being released into the Earth’s atmosphere, and the people transformed by that are called Nu-Humans. We may hear that clumsy term incorporated into this series, but I’d much rather have the far more elegant Inhuman branding."
That sounds like a way to get around the M word, and sounds smart to me. I hope this is how it plays out for the remainder of the season.
