But, is it really so new?
DC has reinvented itself before.
Beware....plenty of spoilers for comics here.
Crisis On Infinite Earths
It restructured DC's Multiverse in ways that are still being felt today. One of the largest changes of the series was that Barry Allen sacrificed himself to save us all....and his protege, the young Kid Flash, Wally West, took up the mantle of the Flash to honor Barry Allen.
This was a pretty bold step for the time, and it shook up the status quo of the DC Universe for decades, and its effects are still being felt today.
...and Wally and the original Flash, Jay Garrick were allowed to establish a bond, with Jay serving as Wally's mentor (and Wally standing in for the son Jay and his wife Joan never had....).
Armageddon And Zero Hour
.....the legacy was becoming a little harder to see, and the old was being pushed aside for the new at times.
Infinite Crisis and Final Crisis
This also caused a bit of a problem...as what to do with Wally?
....and you have a legacy hero of your own with the former Impulse, now Kid Flash?
Not to mention, if you grow up, doesn't that mean your mentor grows old?
....and he was a little different than the original Wally (and had yet to take over for Barry....).
DC Universe: Rebirth
That is the lesson I choose to take out of the new direction for the characters of DC, and as for what we will see and how things will develop, only time will tell how that race is run. It is hard, but to win the race, you also have to start it, and this start looks promising! Still, as with all things, the clock is ticking....and you have to wonder when time will run out.
....a fact as true now, as it was in the Silver Age, as shown on this classic cover by Carmine Infantino and Joe Giella from Flash #163 (August, 1966).
