This was fantastic. I'm an old-timer geezer fan of the original JSA who owns pretty much all their appearances since the early eighties and I loved this book!
The artwork was gorgeous. The writing was serviceable, but at times rather unbelievable. That jerk girlfriend of Jay's was completely over-the-top. I can see this is not a comic that is going to have particularly realistic characters or dialogue, but hey, its a superhero comic. I can deal.
But still, I loved the concepts and world-building on display, and how gorgeously it was illustrated.
That last panel reveal of Jay's new origin was wonderful. He's always been my favourite JSA member so I'm quite tickled that he's going to be empowered by the actual inspiration for his visual design.
