I tell ya - this is such welcome news (not losing Jarv & Tex - tho it seems like Tex already jumped ship, no?), I can't tell you. I was so fed up with the story-that-never-progressed, and Way's obsession with rubbing our faces in "Johnny Blaze is an idiot hick", right up to the inclusion of "his lady Dixie" (I'm sorry... who?!?) That I decided to do what comics companies and creators who don't take criticism seriously when their books still sell and vote with my wallet.
So, for the first time in my 32 years on earth, as of 3 months ago I started not buying new issues of GR. This announcement turned me around, and I showed my appreciation by buying all the back issues I hadn't bought, since the new guy seems to be picking up where Way is leaving off. Course, I also bought Scalped, and couldn't get into it, but seeing as I feel about Way on GR the way most people felt about Chuck Austen on Superman a few years back, I couldn't mind less.
The art... I sense more than a little Pop Mahn, but I think so long as it's inked "gritty" not clean... it could be awesome. Unfortunately, they seem to be keeping the same colorist. I couldn't be less of a fan of the coloring of this book - it looks like it was done with Crayola crayons to my eyes, and GR (I think) needs solid blacks and deep colors, not this sketchy application. That's not to say I don't think this coloring wouldn't work well on another, lighter book, but I feel it doesn't service our boy well.
So that's my 2 cents.
