Yeah, I'm actually a little surprised by how solid all the Absolute books have turned out. The only real criticism I have is that this doesn't really feel like a universe that Darkseid created from the ground up, more like one he might have "infected" with his influence. But, then again...that'd just be Earth-3 or the Anti-matter Universe. All the books we've gotten have been worth checking out on their own merits, though.
My personal ranking is:
1. Absolute Wonder Woman-Agreed. This is probably my favorite of all of them. A great twist on the concept of the character, while still managing to keep the feel of the character. And the last two issues have had AMAZING art. Loving the mythology. Loving Diana's relationship with her adoptive mom. Loving the new takes on the Greek Gods and monsters and magic. This is just a good book.
2. Absolute Superman-This has been a slower burn, but it's actually grown into something surprisingly good. It didn't have the best beginning, but it's been getting better with every issue. It's a interesting alternate take on Superman. A bit more "activist", like Grant Morrison's New 52 run, with a bit more of a sci-fi focus.
3. Absolute Martian Manhunter-This is a very interesting book with a lot of high concepts. My biggest problem is that this doesn't really feel like a "ongoing", to me. This feels like something that really should have a planned ending. A 12 issue miniseries, perhaps. But, I do like some of the ideas this book is exploring. It feels very "Vertigo" in a good way. It kind of reminds me of Shade the Changing Man.
4. Absolute Green Lantern-I'm a big sucker for space stories. And I'm a big fan of Green Lantern. So, this was always going to appeal to me. But, Al Ewing seems to be crafting a interesting alternate take on possibly the entire idea of the Emotional Spectrum. Everything feels a bit more alien and weird, here. We're in the early days, so I could see this climbing up the ranks, as we see more of what's going on and uncover a bit more of this mystery.
5. Absolute Flash-I like this. But, I'm waiting to see where it goes. Being a bit more of a time-travel story is a interesting direction that I didn't expect.
6. Absolute Batman-It's Batman. I'll admit, I'm just not the biggest Batman fan. But, this is a good twist, with old villains actually being old friends in this world. Definitely still worth reading. It's just that I find all the other books more interesting.
If you like these, you might want to check out Marvel's new Ultimate line, too. It's doing similar things with the Marvel characters. The Absolute and Ultimate lines have both been refreshingly unique. Even if both of their "overarching" stories feel like their weakest aspect, to me, at least.
