I bought the book for both the Jay and the Wally story, and I'm actually enjoying where they've gone with Wally. Short of retconning Heroes in Crisis away, the way they let him be heroic and save his children was probably the best way to bring the character back to who he really is. And if he is now supposed to be the one to fix the timelines, I think he's in a lot better place emotionally to do it than Hal in Zero Hour, which we see a shot of in Flash 750. I'm looking forward to where all of this goes next, and I'm hoping with Didio gone, we'll see some better treatment for Wally. Time will tell.
