For my money--which ain't much, but still--J. Michael Straczynski is an amazing writer. His writing on Amazing Spider-Man was inspiring; his brief run on Fantastic Four was innovative; and his done-in-ones on The Brave and the Bold were stunning. (And don't get me started on Thor...) I hope to write posts on much of his work in the future, but now the book of the moment in Superman (though he's not scripting anymore, of course, since the success of Superman: Earth One, which I have to admit I was less crazy about).
(Note: I fully realize that Chris Roberson is scripting the current issues of Superman to JMS' plots, and to whatever extent Mr. Roberson is responsible for the broader ideas within the book, I commend him too.)
UPDATED NOTE: After corresponding with Chris Roberson, I now know that he was actually responsible for most, if not all, of the ideas I discuss in this post. Apologies from Chris for overlooking his contributions before, and kudos to JMS and Chris as an incredible writing team!
The current "Grounded" arc, in which Superman takes a stroll across America (similar to Green Lantern and Green Arrow's road trip in Denny O'Neil's classic 1970s run), has been controversial, to say the least, especially since Superman was not seen--at least not as Superman, and not on Earth--for a year during the "New Krypton" storyline. And now that he's back, he's... walking. I can walk. I know a lot of people who can walk. Walking's easy. Flying, now that's tough. Now who can fly... hmm... let's see...
Nonetheless, I like it. "Grounded" is supposed to humanize Superman, bring him in touch with the common folk, and highlight the problems of present-day America (as O'Neil did in the 70s in Green Lantern/Green Arrow). But I like to think it brings him in touch with moral decisions that he normally doesn't have to make, dilemmas we all face everyday. (I discussed some of this previously here.)
