At least for marvel they are just taking a character who was gay from the beginning and just gave spotlight. what dc seems to be doing is retconned an iconic character (he is the first green lantern, he is iconic wheter ou like it or not) just because. It's not even like dc has no gay characters, they could have gave midnighter, apollo or even batwoman more attentionand accomplish the same thing without pissing off fans and without getting rid off obsidian one dc's more well known gay characters whose relationship with his dad is important part of his character. I know this is a reboot to bring in new readers but this is not ultimate marvel where they could do anything they want with the cahracters as it was created entirely as an alternative for new readers to get into without doing research over ons of backstroy. This is a reboot of the main dc universe, which means it should try to compromise between new and old readers, what they doing is rectonning a long time character just to bring in more readers. I am all up for gay rights in fact i even like characters such as wiccan and hukling, midnighter and apollo and even loved the role question in the 52 comics and i don't see why they couldn't just give their already gay characters more spotlight instead of alienating long time fans of the character.
Okay, i agree Bendis can be a bad writer at times and he can be inconsistent. But seriously it is not his fault, i am tired of people dissing him. If you read his street level books, you will be able to see that he is a great writer, the problem is that marvel can't see that bendis can't write non-street level books to save his life. It is almost the same thing with Fraction, his iron man and thor are good but he obviously can't write team books (x-men).
So if there is anyone to blame it should be marvel not the writer himself.
