Barry has a tradition of reboots and changing comic book status quo's. His creation is often heralded as the creation of the Silver Age in 1956. He helped found the DC multiverse when he ran so fast he popped up in the world of the previous Flash, Jay Garrick. His death in Crisis on Infinite Earths is often cited as one of the marks of another new age, the end of the Bronze Age and creation of the "Dark" Age. His return to life a couple of years ago began a story that ultimately ended the previous version of the DC Universe. And now, in the New 52, he's got his own title again.
And it is beautiful. No, really, the art by Francis Manapul (who also co-writes the series) is downright gorgeous, and is second only to J.H. Williams III's art on Batwoman. Barry Allen's been regressed a little bit, he's no longer married to Iris West for instance, but he's not a brand spanking new hero, he's been around for a little while. A mysterious group (there's that term again) has gotten an old friend of his in trouble and are using copies of the friend with powers to do their dirty work, and it's up to Barry, as a forensic scientist, to clear his name and get to the bottom of the mystery.
It also has the blurb. In comics from the later Silver Age up until the late 80s or so, each issue would begin with a brief paragraph summarizing who the hero or star or team were and their mission, introducing the reader to the character and situation as though it were his first comic book. Which often it was, comics being a disposable medium for decades in the US. It's just a nice nostalgic surprise.
So, Barry and Iris aren't married, anymore. They do flirt a good deal, which is cute. Probably the best handling of the "vanished marriage in comics" in recent history. They have nice chemistry, and it's hinted that they'll get back together, which is cool. The story and writing on the book has been pretty good to excellent, with plenty of cool applications of the Flash's powers (in one case VIBRATING A JET AIRLINER THROUGH A BRIDGE to save it from crashing--two words: awe some!) and the mystery is engaging enough to intrigue. The Flash is definitely one of the better books in the New 52. Don't miss out just because you're irritated that Wally West is missing.
Aaron "The Mad Whitaker" Bourque; Wally's been missing before, but he's always come back!
