Weridelves points out some of the clear issues with the series, to my mind as much to do with the authors style as to do with the filming, i would like to rebut some of those points....
""I think it loses an awful lot by never having the core characters interact with each other that much, it makes the whole show feel a little incoherent to me. And I guess the acting and writing is a little more trashy than I'd have wanted. The most frustrating thing for me is this idea that it's just always building to something without any real payoff, it makes for very unsatisfying viewing.""
I think Tyrion Lanister and Arya Stark serve as the authors vehicle to tie the characters in his tapestry together. One could almost stipulate the series is written from their perspectives...as they are among the few survivors.....and that seems to be key in the "game" that very few survive interaction with the "throne" for long, few players in this game have the skill of Littlefinger the coin master or Varyas the spymaster who live in and around the throne daily and actually thrive there. The series has been described as a fantasy Sopranos, wherein characters die off at an alarming rate(avg 14 per episode) and while this can be alluded to as a downfall of the series(excluding HBO's predilection to sex it up) i think it speaks more to the authors intent than any true failing of the tv series. This author loves to serve up interesting characters, develop them to a certain extent and then kill them off before our eyes. We buy in to the character and his/her world and then the rug gets jerked out from under us time and time again, this is not normal fantasy writing...or normal novel writing...hell he has thrown the contract with the reader right out the window...and yet it fits.
Striving for the "throne" is a grisly buisness fraught with failure and death, only one can be king of the hill at a time, though many strive for it and as soon as you claim this prize you are faced with all the contenders instantly. Perhaps it is why Arya and Tyrion survive, they show little interest in claiming the throne and instead seek their own survival and place in this fantasy world...little wonder that we like them both so well.....viva la throne
