I am not convinced that MMH is a better character for a JLA movie than Cyborg, or even a better character period. As I see it, people came out of nowhere crying some nonsense that MMH was the most important character in the JLA because he got replaced by Cyborg. DC is trying to cater to a broader demographic by including Cyborg in their main seven, but whenever something like that happens in the world of comics, the readership keeps crying and moaning about change, and wanting to read the same jargon over and over and over again. That is my main problem with comics, and why I feel they won't progress.
I want you guys to recommend me some MMH stories. Either stories of his own, or JLA stories where he's the main character. I hope they're good.
