The first issue intrigued me with its imagining of Mars as a place familiar enough, but very alien. Though it synthesized elements of J'onn Jonzz Silver Age origin, the 1988 DeMatteis/Badger "most everything you know is a lie" limited series, and the Ostrander/Mandrake ongoing from 1998, it add new stuff to it, and looked it the old continuity from a new angle. It also revealed that J'onn J'onzz on Mars was a dirty cop.
I am happy to report the first issue was not a fluke. The second continues to be just as interesting with its parallel stories on a murder investigation on Earth and J'onzz's life on a doomed Mars. As life continues mostly as normal for the "manhunter" and is family, tension has begun to creep in. The deadly Curse of H'ronmeer is spreading. Rossmo's art really adds to the alien sequences, but is adequate in the more True Detective Earth-bound portion of the story. The coloring style seems to shift a bit between the two sections as well.
It gets bonus points for providing an explanation for J'onzz's bettlebrow: a brief Martian Neanderthal-mania.
