I know there are multiple threads about these two books on the DC Comics forum, but there has been so much advance discussion about these events on the Batman forum, I thought it might be desirable to continue the discussion here as well. The plots of the two books are so intertwined, I think a thread which allows for discussion of both might be helpful.
Personally, I had a lot of reservations about Earth Two after I heard it was going to have rejuvenated heroes. My affection for the JSA was always largely influenced by the original team's World War 2 context. I wasn't sure I was interested in reading about a young Jay Garrick, etc. But I was willing to give it a try.
I'm glad I did; I loved this book. Of course, I knew Nicola Scott's artwork would be top-notch; she's doing some of the best work out there, IMO. Robinson is less predictable; some of his stuff I've liked, other stuff, not so much. (How many people remember that he was the first writer on the JSA book, several months before Johns took over?) But I thought this was very well written. Seeing the trinity all killed off midway through the story was unexpected. And the first looks at Alan Scott, Jay Garrick and Al Pratt were all very intriguing. Not sure exactly what I was expecting here, but this wasn't it. But so far at least, I'm liking what I see a lot and am on board for the foreseeable future.
As far as Worlds' Finest was concerned, again, I knew I'd like the art. Neither Perez (on modern continuity) or Maguire (on flashbacks) disappoints. Levitz is another person I've had mixed experience with. I simply don't get excited about the Legion, and that's so much of what he's done recently. And I read one issue of his Huntress mini before dropping it. But no complaints at all here. Great characterization and I liked the way the girls worked together. The careful connection to both Earth Two and Mr. Terrific was appreciated. (And who else is thinking that, before Michael's machine was destroyed, it took him to Earth Two?)
Personally, I've been reading more DC titles since the dawn of the DCnU than ever before and have been trying to drop a few (and I have recently dropped both Batwoman and BOP). But darned if I'm not going to be picking these up now. As long as the current quality holds, these are keepers IMO.
