Yeah, I loved Max in JLI.
He went from being a carbon copy of JR Ewing and Donald Trump and evolved, by the end of the first year, into a strong character. And even had J'onn scan his mind and found no evil intentions.
Then he was given powers during Invasion and imagined himself as a hero, while with his girlfriend, Wanda.
He even showed that he had reservations about spying on Booster when he joined his ex-wife's Conglomerate.
So I'll add the Didio-fied Maxwell Lord to my list of characters I dislike.
