As much as I respect Geoff Johns, I'll never forgive him for being responsible for Wally being essentially shelved for YEARS.
I guess this falls into MUH FLASH/NOT MUH FLASH territory, but...both Marvel and DC should consider their audience. Most people who are into comics these days grew up reading 90's and early 00's comics.
But they're not. They want the new, casual readers and they're not really buying their new, hip comics.
I'd probably look at what people actually want instead of forcing what a small section of fans (who probably don't even read comics) want.
Personally? I'd love stories. Long form stories, single-issue stories, just good stories and good art. I'd love an escape from everything I'm seeing on the news. Give me fantastic, unrealistic, but well written and well drawn comics, like what drew people into comics in the first place.
DC's Rebirth touched on this. I was skeptical about bringing in the Watchmen, but it's working. DC feels exciting these days. Marvel...there's some select titles that I love.
However bad the first issues Jane Foster as Thor was, the current stuff has been FUN. The recent Asgard/Shi'ar War story arc with the Shi'ar gods was absolutely fun. Infamous Iron Man, even with Bendis, is a fun look into the mind of Victor Von Doom trying to redeem himself. The Ultimates has a very diverse cast, but that's not the focus. The focus is STORYTELLING and it's been fantastic. I wouldn't have bought Good Guy Galactus (apart from Hickman writing him) but here we are. Al Ewing's been experimenting with continuity and explaining a lot of continuity gaffes in the process, and this is the type of Cosmic Marvel stuff I've personally been missing since DnA's Guardians ended.
And as controversial as Steve Rogers: Captain America has been, it's actually a damn good look into how much Steve's been altered. It's like a train wreck. And goddammit, it's been written well.
As for DC, the recent Button story arc and Superman regaining his pre-New 52 history have been really, really good reads.
Marvel's gonna try the Legacy thing with Generations. I HOPE it leads to more good titles, because lord knows they need more of those these days. I was all for Amadeus Cho as the Hulk, but they didn't need Bruce dead. Same with Tony (well, he's comatose, but STILL), Thor, Cap being Evil, Wolverine encased in Adamantium and suffocating...at lest Peter Parker and Miles Morales coexist. As do Richard Rider and Nova. And Carol and Kamala. Marvel has a lot to learn about Legacy characters, but I hope they're not following DC's example.
