I'm surprised there are that many positive "A" votes.
I think Azzarello's run is critically acclaimed primarily because of it's divergence from the history /conventions of past Wonder Woman eras and arcs. I agree with the poster above who said this reboot was made cheap for the sake of shock value. I think when this run is complete and all the readers (and critics) have had some time to reflect on it, it's ranking will substantially drop especially with repeated readings.
Right now it is viewed in high regard because it's one of the few reboots of the nu52 which didn't begin with a complete mess.
The plot - 5 - Azz had a plan and he's stuck to it so far, making it at the very least interesting to see where it ends.
The art - 4 ; Chiang has had some good issues but a lot of mediocre ones filled with spare, simplistic panels.
The characterization - 2 ; Brutally deficient as covered above
The dialogue between characters - 6 ; Azz has had fun with modern re-interpretations of mythos characters. Some dialog was witty and funny.
The action - 6 - I think the big battle (#23?) with the first born is the highlight so far.
The pacing - 3 ; In an era where whiners complain about decompression (Bendis), it's funny how many accept the pace of WW which is sub-glacial in comparison. Reads better as a trade.
