I mostly enjoyed the books. Unfortunately I learned about half way through the first book that you can't get invested in the plot with any hope of there being good guys and bad guys and maybe the good guys will prevail. If the show ends with Cersei flying around on a dragon carrying Jon and Dany's heads on spikes while fucking the dwarf, it wouldn't be far fetched or out of any realm of how fucked up GRRM is or his control of the plot. It is entertainment, it is better than reruns of Friends or another bullshit episode of the Big Bang Theory. It isn't real, I don't expect it to be or for it to be accurate or make sense.
