I appreciated Dany's chapters more on the re-read, and I do like articles that have been written about that plot. Ultimately I think the big issue that turned many people off was that Tyrion never reached her. The dominant assumption about ADWD was that Tyrion would reach Dany, and not getting that moment soured people on both of their POVs imo. Personally I thought Tyrion's chapters were very strong.
Besides the issue of ridiculous names and less-than-interesting support characters, the big problem about Dany's chapter IMO was that...she's does a bunch of dumb stuff, and it's stretched out over too many chapters. While I like the chapters more than I did on first read, I still think her number of chapters could have been cut by 3-5. She spends a lot of time making puzzling decisions that make her rule less interesting than it could have been.
For instance, why didn't she leave a force to rule or at least protect Astapor? The previous books are full of characters who realize they cannot leave un-manned or enemy castles/towers/etc to their flank or backs; Stannis had to take Storm's End to open up the possibility of taking King's Landing, Robb had to re-take the North, etc. Yet Dany never seems to consider leaving someone behind to rule in her name, or sending support when Yunkai attacks. It just doesn't make any sense. If such an issue came up in Westeros, we'd at least get a few pages of debate amongst the king's advisers. With Dany it's just "no thanks I won't help you, good bye. Time for Daario and Hizdar."
I can't help but think things would have been more interesting if someone was sent to Astapor, and we got reports or even a POV view there. Imagine what Tyrion's reaction would be to Dany's decision on this; he criticizes her siege tactics in ADWD when he realizes she didn't poison the wells outside of Mereen.
