I agree that Dan Slott has been amazing (pardon the pun) on ASM. But I pick and choose and trade wait. Is Spider-Island his best so far?
As for GL, well, I used to buy this monthly pre-New DC 52. But now that Sinestro's taken over the spotlight (not that I don't like him, I do but he is not Hal, not my GL, anyway) and Hal seems to be playing the sidekick/Peter Parker role now, I'm giving it a rest. But I'll surely come back to GL. Like I always do. My favorite series in the last decade. Geoff John is perfect on GL. He's a hit and miss for fans (and I'm one of them). Comes up with cool concepts and ideas but sometimes he comes off like serving the fanbase more, feeding the fans what they want, instead of giving us solid stories that have everlasting impact.
I mean, Captain Planet and the Planeeters-inspired GL Corps and rainbow corps?! And Blackest Night is like his excuse of turning every super hero into a corps member. Still, BN is much better than Marvel's Fear Itself, which to me is like House of Uninspired Ideas copying from Geoff and DC.
And Justice League isn't that great a read. Not much of a plot, really. But who could resist Jim Lee's art, right?
Overall, DC's been successful in reaching out to the fanbase. And they're not charging us a bomb.
Well, yeah, New 52 is like the 90s all over again. Cheap gimmicks, fan favorite creators, Bob Harras (!)... but at least they got the fans' attention. And the mainstream as well.
Marvel? Well, go ahead and continue to charge us $3.99 and double ship and employ less than superstar artists and flood the market with more and more Avengers stuff. The fans have accepted former EiC Joe Quesada's challenge. "Don't like the books, then don't buy them." Thank you very much for the great advice. And us fans who go online and post our thoughts and comments "don't matter"? Well, look who's smiling now?

(For the record, I admire what Joey Q and co. have done on the creative level. I just don't agree with their marketing and business plans)
