There was a lot of outrage over Harley's new look, Floyd Lawton's missing mustache, Amanda Waller's...slimmer figure and much more, but guess what? All of that was before the book ever even came out. Since then you know what's happened? People who were trashing this book either didn't bother to read it, or they read it, and were pleasantly surprised by how good this book has been. I was one of those doubters, but I gave this a chance because I love John Ostrander's original run on this book, and I'm glad I did.
In some ways, Suicide Squad encapsulates what the New52 was all about. An old concept, modernized and turned on its ear, but done well, with a fresh take on the concept and a solid delivery month in and month out.
This really is one of the great successes of DC's current universe, and if you're finding yourself looking for something new tomorrow, maybe go back to last week's books and give this one a shot (well, issue #6 is the beginning of the arc, so start there), you'll be happy you did.
