To the OP question. Yes I felt wasted my money and time. Worse DC's whole way of their message for Rebirth...ie to suggest if you liked the new 52 you somehow not a real fan or the universe never had love or hope when that is absurd because there were good stories. DC simply needed to keep building and stop dragging some good books down with crossovers etc.
Killing new 52 Superman, then wiping out Azz's WW sort of was the last straw for me. From buying regularly I am not buying anything. Rebirth JL is just poor with the current lineup. SM playing dad to a kid overnight I have no interest in nor Rucka's loopy WW. They just not the versions I am interested in. DC giving lapsed buyers what they want....fine but they are not even trying to give other fans who might want something else another option. The multiverse is there to be used and seems like they want to kill it too. DC seems it's this way or nothing. And I think once Rebirth hype dies down DC will find itself no better off because they would have just back pedaled to alienate another group of fans.
