You have much to look forward to. Stick with it.
If you feel like the "good guys" are getting a raw deal, it's likely because you're focused only on the struggle for the Iron Throne in Westeros. If you look at the big picture, and count how many of them have actually died, it'll help give you some perspective.
To the point I have read thus far they all died... ALL OF THEM., well almost.
I won't even say 'good guys', just those i connect with/ root for... I won't list those i liked so to not spoil too much, though I guess it's already past that... but only two characters i really enjoy are even left in the series midway through book 3... and I have enjoyed quite a few... and My sister-in-law gave away that one of the two that are left almost certainly dies at the end of the latest book... Right now i am feeling a bit cheated with the past three weeks of reading I invested to be honest...
I will give Martin this though, he knows how to tell a compeling story from multiple angles, and make you connect to multiple characters... not an easy thing to do... I just don't see why he insists on killing all of them while taking exactly one of the the many I have been wanting to see die... and even he didn't die violently... sonofabtich!!!!
I do like how it is minimal fantasy... altough I also wish he would leave the little fantastical elements he does have out... yes, I know it's fantasy, but that is what kept me from giving it a try for so long to begin with...
I know this much... Fekin Jamie needs to be ripped open and Cersei needs to be forced to eat the innards….. before being burned…
…..
anyway...
