The thing I wonder about Rebirth, is how they explain the difference in histories and origins. The new iterations are too dissimilar to the old. I’ve seen people say that “both are canon”, but that can’t work, and to say it does anyway is lazy writing. I can’t be the only one who sees this; what are they choosing to keep and what are they tossing away, with a few characters in particular? In Superman’s case, they’ve apparently ignored much of the New52 retcons, which I’m all for. But in the case of certain other characters, I’m less than convinced.
Me, I haven’t read much DC since James Tynion IV decided Cassandra Cain wasn’t important in her own origin, and everything had to revolve around an unnecessary newer character. I don’t see how they can say this “Orphan” is the same Cass, when they have such starkly different beginnings and influences (and fathers). “Make things completely and just say they’re the same” barely works in theory, let alone execution.
