I know, but people were saying a lot of the same things about ADWD (seriously, go back and read some of PD's pre-ADWD posts for very similar lists) and look what we got. Granted, ADWD was technically the second half of one big book, so maybe people were expecting more storyline resolutions than was possible given the timeline. Still I think there is no disputing the fact that George has done the opposite of "tighten, tighten, and tighten some more" with these last two books and I don't see that changing. I'd love to be proven wrong though.
Agreed, many of us figured there were basic plot points that had to be addressed...and a lot of stuff simply wasn't addressed such as Robb's letter or Coldhand's identity.
Then of course there were the theories and predictions that didn't come to pass, mainly Tyrion and others reaching Dany; I think many people were so disappointed by the book because it didn't featuring these type of plot points or revelations (ie Jon's mother) that they had been anticipating for years.
The Mereenese Knot George spoke about so much still hasn't been fully cut - Dany met
one person who set out to meet her in AFFC/ADWD. Tyrion and Victarion are very close to Mereen now but a new layer of plot has been added to make their journey harder - ie open war. And while some obvious pieces seem to be in place (for instance, Victarion using his fleet the break the blockade, or Dany receiving help from Tyrion's group to break the siege on land...after ADWD perhaps it's safe to say nothing is obvious or a given. Perhaps the only thing that can be said is that the time of diplomacy is over for Dany and others, and war (and winter) is officially on. Which means more action
It's hard to see how he can possibly finish this in two books, given what happened with AFFC/ADWD. Both of which I really liked, and certainly a lot of stuff happened, but just not the stuff that could have advanced certain major plot points. It's somewhat funny that all while Dany is dithering with Mereen, dithering with dragons, and now apparently dithering with another Dothraki khalasar, Aegon ran into Tyrion and was tricked into heading for Westeros ASAP. AND he's already conquering shit without dragons or any support from major houses.
