I doubt I would buy Maximus if he were released, so for me, the Inhumans are complete. I’m just not all that steeped in the lore. Most of my exposure to the Inhumans growing up, outside of Crystal, was as guest stars in other books.
If they consider the Inhumans complete I'm going to spend too much time and energy trying to build an ANAD Karnak for myself. There's gotta be enough parts to pull that off.
There was a 12 issue Inhumans maxi series that came out several years ago that was very good. It was written by Paul Jenkins and drawn by Jae Lee. The artwork was real purty. I believe it's still in print if you want a good read.
War of Kings is amazing. Not only is the writing top-notch, but Paul Pelletier’s art is always exquisite. Couple that with Gladiator having such a central role and I reread it quite often.
I really liked the Inhumans series when some of the newly transformed Inhuman children/teens became foreign exchange students. There were some powerful characters created for that run.
