He was not only the mastermind of JLI, but also helped give us both parts of Green Lantern: Emerald Dawn (still the best GL origin ever)

What I like best about the Emerald Dawn series is the risk it took with Hal's character. Certain... shall we say... current takes on pre-GL Hal have him as a fuckup-martyr, a guy who has made a couple mistakes but is ultimately suffering because of others. While Hal was scarred by the death of his father in Emerald Dawn, it was very clear that he made his own choices, and other people suffered because of them. He screwed up his job, he screwed up his relationship with Carol, and his decision to drive drunk resulted in a friend being paralyzed due to the resulting car accident. That's way more Marvel than most Marvel characters.

Also, modern Sinestro was introduced in Emerald Dawn II. Geoff Johns gets a lot of credit for making Sinestro a badass*, but from what I can tell all of the character notes that he ran with were introduced by Keith Giffen and Gerard Jones. Desire to impose order on the universe? The relationship with Hal? The reason why he fixated on Hal above all other Lanterns? Those are all found in ED II.

*-- I'm not saying he hasn't written Sinestro as a badass, but Giffen and Jones did all the groundwork, and I haven't heard them get any credit for it.
