Sounds like Martin’s developing “Jordan’s Syndrome”.
The first three books were great, but I also liked the next two as well, though they weren’t as good as the first three obviously, with the fourth being the weakest.
I’ve read all five of them twice, but I now no longer care if he ever finishes the series.
I am no longer concerned whether or not Martin dies before he finishes writing.
I am far more concerned that I am going to die before Martin finishes writing.
Also, there are some theories out there that the reason Martin has never finished the books is that he got his little pink panties all in a wad because during the wait for him to finish, fans have figured out his big super secret plot twist involving Snow.
So now he is punishing those fans by not finishing.
That theory holds water for me. Martin is a vindictive bitch democrat, so sounds like something he would do.
