My favorite thing about the issue was how it established Ginger Wally as the heart, Barry as the brain, and Nu Wally as the rookie of the Flash Family. The dynamic was effortlessly set up in a single issue, which makes me even more frustrated that Scott Snyder still can't set up his personal creations properly.
I think that with Jay as the wise veteran hero, and Bart as a hyperactive powerhouse, the Speedsters can be an even better superhero Family than the Bat-Family even. Since they wouldn't be as bloated or derivative.
