Yes, I did read past the first few issues, I read all of it, and felt greatly rewarded. Yes, it was a different angle to examine the idea of J'onn J'onzz, but by the end he seemed very much like the stalwart, heroic Martian Manhunter we all love.
I loved the myth-building that was happening throughout the series, borrowing from previous iterations and adding more details on top of those we have seen. The customs and procedures involved with J'onzz's shape-changing and telepathic powers were so flavorful in concept and evocative in appearance. I loved the whole series.
