The webcomic Comic Critics takes on Flash: Rebirth.
I’m Just Sayin’… is extremely unhappy with Flash: Rebirth #1, particularly in terms of characterization. I particularly like his point about Savitar, whose entire motivation was that he wanted to become one with the speed force. Watch out, though: the post starts with spoilers for the latest Spider-Man.
Rikdad looks at DC’s history of revamps starting with the transition from the Golden Age to the Silver Age.
The Absorbascon contemplates labeling of comics ages, concluding that the Iron Age ran from 1985-2005, and that we’re now in the Platinum Age — all about bringing back the brightness of the Silver Age that was thrown out for Iron.
Gentlemen of Leisure profiles the Flash with an emphasis on Barry Allen and his legacy.
Slightly off-topic: ICV2 talks about old pop culture icons — the ones who, rather than having a nearly-continuous history like Superman or Batman (or, really, the Flash, who despite a couple of breaks in publication has had a regular presence from 1960 onward), keep getting reinvented from time to time like Zorro, Flash Gordon, Buck Rogers or the Phantom.
