It's safe to say that I did not expect the "War of the Green Lanterns" story to end the way that it did. We often talk about "shaking up the status quo" when it comes to comics. I think it's safe to say that Geoff Johns has done just that.
Sinestro is an interesting character. When he started out he wasn't really anybody. He was just a Green Lantern villain with a yellow ring, a ridiculous mustache, and an absurd set of clothes.
But over time he really has matured into a nuanced character. I'd even say that Sinestro is a more interesting and more complex character than Hal Jordan. And that's what makes giving Sinestro the starring role in the relaunched Green Lantern.
Sinestro vs. the Sinestro Corps. How is it that we're only getting this now?
