If you're upset because it just happened in the TV series, just imagine the emotional investment of people like me and myriads of others who have read all of the books covering THOUSANDS OF PAGES. It was a bitter pill to swallow when Martin killed off John Snow, one of the few "good guys" left... this on top of killing off Brieanne of Tarth; it was devastating. At that point I almost gave up on the story/books because "what's the point" of continuing (nearly everyone I care about, Martin kills)? And just think of all of the other characters the readers grew to genuinely care about that Martin has killed off! With John Snow's demise it was like the "straw that broke the camel's back". That said, I will probably still read the next installments IF Martin stays alive long enough to complete writing the books. At the rate he is going between writing the books ether he will die or his readers could before the books story is completed. However, will there even be ANY characters the readers even care about left to warrant reading them? Who knows, maybe John Snow will make a miraculous recovery... However, IF that happens would he still be the same man the readers like and care about?
Sadly, thus far the one word that best sums up the entire GOT series for me is: "depressing"; and that is not a good motive for continuing to read GOT, but we shall see.
They had better not kill off Tyrion Lannister, my favorite character. He always gets the best lines in the show, and delivers 'em perfectly. Love the British accent coming from this New Jersey native (Peter Dinklage), too, lol. I think he may be one of the few American actors on GoT...
