(Spoilers Everything) Why AFFC and ADWD may be masterpieces

There are many fans of ASOIAF that see AFFC and ADWD as "the worst ones" or "the boring ones". I'd like to counter this idea by proposing an explanation as to the reason why these books were structured as they were so that we many better appreciate Mr. Martin's work.

One of the main arguments as to why the previous two entries into the epic fantasy book series are inferior to the previous three, is that they are boring. While, yes, the pacing of these two books did decrease significantly, I would hardly call it boring. You know what other work was derided as boring before the full series was complete? The Empire Strikes Back, which is generally believed, now, to be the best film in the series.

AFFC and ADWD both contain some of the most intriguing thematic and character studies in the entire series, allowing us to delve deeper into the psyches of different characters. One fan theory I saw on here several months ago, claimed that the reason for sporadic books having epilogues is that it might signify the ending of a story telling act.

AGOT, ACOK, and ASOS, would be Act I, AFFC and ADWD would be Act II. Characterizing the two books as the second act of a three act structure really helps me appreciate these two books more. As the second act, it is the period where tensions rise and the pieces are put into play for the climax. Instead of viewing AFFC and ADWD as sequels to the exciting ASOS, perhaps we should instead view it as the culmination of action leading up to the climax of The Winds of Winter and perhaps the falling action of A Dream of Spring.

Many people characterize Brienne's lengthy chapters in AFFC as boring, however I actually prefer the slower pace of these chapters. It allows us more time to really get to care about the character and to see the world through her eyes. As well, her travels help provide us the needed and often disregarded opinion of commonfolk, which eventually does lead to plot relevancy in the rise of the High Sparrow.

Also, the Ironborn chapters are actually pretty enjoyable. I may be biased, as an ironborn fan, but the characters of Aeron, Euron, Asha, and Victarion are actually quite well portrayed and the Kingsmoot scene is still very popular among the fandom as shown by how many people want to see it in the television series. As well, though there were likely too many Dorne POVs, this subplot is also leading up to quite an important plot of allegiances.

Moving onto ADWD, we see less criticism but there is still quite a lot. Most of it revolves around the oh-so-hated city of Meereen. However, along with the highly praised Untangling the Meereenese Knot essays, they also serve to show Daenerys' inner conflict in attempting to be both a good person and a conquerer/invader.

The addition of Quentyn to the story was necessary as it provides the necessary reasoning for Dorne to switch allegiances to Aegon VI, along with Quentyn being an all-around good bloke whose story arc shows the failures of a real adventure and the psychological toll it would take on a person.

Barristan Selmy's chapters near the end of the book are also some of the best in the entire book, despite his POV being an addition solely to untangle the Meereenese knot. Barristan's chapters are filled with political intrigue, betrayal, two-faced schemes and very questionable allegiances.

Theon Greyjoy's arc in ADWD is one of the greatest in the series as well.

TL;DR What do you think? Years from now when the series is complete will these books be viewed more positively or am I a GRRM fanboy blinded by my love for this series? All opinions welcome. :)
