Once upon a time I thought Geoff Johns was a great writer. Now I mostly see his limitations. His plots lack depth and storytelling lacks grand imagination. I think his writing is more reminiscent of good fan fic.
I also have issues with his editorial decisions. New 52 is mostly a mess that has harmed more characters than it has helped. And why does Johns insist on shoving his preferences down our throats? Hal Jordan and Barry Allen, namely. I like Barry well enough, but what has been done to Wally West is a disservice to a once great character. And his Hal Jordan is terribly unlikable. I've never been much of a Jordan fan, but in Johns' hands, Jordan is an arrogant jackass who isn't all that compelling. And I don't know if this is Johns' doing, but the over-saturation of Batman has become beyond annoying.
I would like to further comment, but I've stopped reading much of Johns' work. I can say that I stopped reading Justice League because of how hollow it was, and because I couldn't stomach his portrayal of Superman. I don't know how the title is faring these days. I will, however, be picking up his Superman run with Romita, only because I love Superman, like Romita, and hope it will be more like the Superman from Pak's Action Comics, which is the best thing to happen to Clark since the New 52 began.
