So, what did you'll think of issue 13?

I thought it was a brilliant concept. Yes, at its heart, it was a pretty vanilla idealistic "war is evil, give peace a chance" story, but the reincarnation angle gave it an intriguing twist. It was kinda like 'Groundhog Day', with reincarnation instead of time-travel. I got a pretty strong 'Edge of Tomorrow' vibe from this story.
Of course, what could have been more intriguing is if Carter (or whatever his past life's name was) ended up fighting an enemy soldier who's another one of his incarnations. Given that its now established that he doesn't have to reincarnate chronologically, I think this was something they could play with. But instead they opted for a simpler story of him dying over and over on either side of the war, subconsciously remembering enough to humanize the other side in his mind, and finally deciding to make a difference. And ultimately, this story worked out perfectly.
The big highlight of this issue is the return of Hawkgirl - or rather a past life of hers called 'Sherra'. I think they really need to explain how Hawkgirl fits into the new origin, but in the meantime these appearances by her other incarnations might be a good way to include her in this book without stepping on the toes of Snyder and co.
