Really disappointing, too much dispersion

We love this saga for the psychology of the characters, to the relevance of intrigue, twists to this fantastic peak never too excessive for the complexity of this universe and the interaction of all these figures why complicate more ??

A do we need of seeing how this power struggle iron islands Greyjoy following the father's death or a vain Myrcella kidnapping attempt in the desert of Dorne or daccompagner long crossed Samwell boat when so many are dintrigues left unfinished elsewhere in Westeros and beyond the Strait.

I think George RR MARTIN disperses; in this integral, it further expanded léventail characters and intrigues which immediately adds the interest is questionable. I want to believe that the relevance of these new plots will be later, but i doubt. It starts in every sense too.
Dailleurs sen author realizes he admit I was completely overwhelmed by the number of pages that saccumulaient during the writing and it turned regained forced to divide what should be the 4th volume in two volumes: 4 (900 pages) some southern character Westeros, 5 (1200 pages) all others.

The question of whether George RR Martin will be able to finish his story one day really pose?
Especially sil we add to this the TV series that also involves the author dune significantly.

Knowing that the series is filming Season 5 and Season 4 is riding on integral 3, 4 and 5 same seems to have no doubt today about the fact that the events that will unfold in the series will exceed the intrigues of books.
If the plots are revealed by lead in the series, the author he will take the time dachever books?
Not sure!
Really disappointing.
