I'm doing the same, just finished Reign and am moving into Return. Also read Lemire's Royal City which I liked although the ending felt rushed.Reading the Death of Superman for some reason.
In the "newspaper" about his death there's an ad that says "Things Are Booming in Coast City"
lmao
I mean, he's largely correct about the Avengers only usually having one amazing book between them at any one moment. On Wonder Woman, the biggest issue is most of her focus is on the gods, and recasting them over and over to fit the new story. Which is the point of the best WW arcs, of which I can only name a few. But you can only do that so many times.
So it's probably a problem of finding a WW-unique hook. For a bit there in around 52, it was the fact that she was the one who would occasionally go that extra mile and put down a villain. (The Max Lord moment.)
EDIT: Breevort points out the gods and monster problem in another reply.
Writers don't know what to do with Diana in the context of the Trinity. Batman and Superman play off each other perfectly, and they both have fairly fleshed out "worlds", but Diana hasn't really had a strong relationship with either one that didn't cast her as the love struck wannabe girlfriend for either Batman (DCAU) or Superman (Kingdom Come). Patty's movies for better or worse are the things that's going to define a lot of Diana's lore going forward, because DC can't make up their minds on who WW should be.
Rucka's Rebirth run was fairly good and if DC had actually bothered to get a good creative team before running through a bunch of filler teams + Robinson it could've really been a launchpad. But just like Morrison's New 52 Action run, the follow up was rather weak. I really hope Orlando can turn the ship around.
