Seems the consensus of Infinite Crisis is a unaminous "meh". I like Geoff John's stuff usually but not this. For me there was no story that could be good that killed the original Superman. Like the first Crisis, this was a clunky story. For the amount of characters that was almost unavoidable but unlike the first Crisis this one couldn't let the GA Supes have any type of happy ending. Good stories build to satisfying conclusion. This one just killed off a legend & ended with an evil twisted Superboy. Yeah the big three are friends again but that doesn't come off as very satisfying considering the losses.
The final spread with all the heroes doesn't really work. Lobo & Black Adam? Some have modified costumes that are not improvements like Shazam's hood & whatever Uncle Sam is wearing. Sorta interesting seeing Starman & a Batgirl in there but overall I was left feeling less than impressed.
I'm ready for the next Crisis myself. Like the evil Superboy, I think it's time for DC to just start over. Maybe something like Marvel's Ultimate line. They could continue publishing this DCU but start another one building from the ground up.
