I like the Parallax retcon. Not just the results, but I like the idea. I think that Emerald Twilight was abrupt (though yes, there were some character moments prior to it that screamed "Not normal"), and that mind control explains it perfectly. I have no problems with the cheesiness of a giant yellow grasshopper (fFROM OUTER SPAAAACE!!!) with the ability to control minds, possess bodies, and instill fear in the hearts of sentient beings. We're talking about superhero comic books here, after all.
I think the retcon fits seamlessly into continuity. I don't think it ruins the previous stories. I even think that there are points where Ron Marz left the option out to explain Hal's behavior as the result of mind control/possession (Emerald Knights) so it fits very well in there. I think it is awesome to have all the Lanterns active, and the GLC back.
I like that it was the Guardians fault this thing got out.
I don't mind the re-explanation of the yellow weakness.
I don't think that Hal needs to be responsible or punished for his actions during and after Emerald Twilight. He's a comic book character.
I don't mind that he's angsty over the Parallax thing. Or that he lost some face. Or that he gained it back.
I think it was cool that Kyle got possessed, because that was always his big fear.
I like the Fear theme to the Green Lantern franchise. I find it relevant to today's society. I find it comforting to escape into a story where a hero literally has to wrestle with willpower and emotions.
I kind of like that the emotions are represented by colors and big psychic energy organisms.
I find it fun and appropriate that, when revealed, that the Personification of Fear is a fucking absurd concept that nevertheless would make you shit your pants were you to meet it.
I'm not saying Geoff Johns is a genius. I'm not saying that we are wasting our time discussing comic books. I'm not saying there's anything wrong with you if you disagree with me.
I'm just saying that I like it, and I would like the commenters who don't like it to avoid pissing in my cheerios when I'm happy over Green Lantern. There is precious little that I get joyful about, and I would like these feelings of joy to be sustained as long as possible.
