Do you like Martian Manhunter? If not why?

Martian Manhunter was probably DC's most underused hero in the 1960's and 70's - especially under-explored was his power to become invisible and his telepathy. More recent decades have seen his character developed much more and it is a testament to the character that he is the only hero to feature in every incarnation of the JLA. (He even held the disaster that was Justice League Detroit together!)
Yes I like MM and it is good to see him being utilized in ways that show he is not just a green Superman!
