Books 4 and 5 were damn solid
I might give you 5, but 4 sucked. 5 was by no means worth the wait. Having read a bunch of Martin's other stuff, I can already see indications that he's going to pull one of his in/famous gotchas.
He's pissed all the fans figured out his big reveal, and now, he's going to change everything around to the detriment of the story.
He's immensely talented, but he is in severe need of an editor to ride his ass.
When authors begin to wax poetic about food and turtles, they need a damn editor.
I guess I'm just sick of epic fantasy. I find old school, tight, stream lined fantasy so much more appealing these days. Less exposition more action.
