I think that's a much better way to start. Martin is clearly a discovery writer, but he talks like he's a plotter, and the intricacies of the political machinations imply he's a plotter, too.
He's written such a tangled mess that it's impossible to untangle everything. Plus, he's made his millions, so there's not much incentive for him to finish.
I started reading when book 5 was about "due" based on his expected release date he had previously announced thinking that book 5 would likely be out by the time I read up to that point. Over four years later book 5 finally released and I knew in my soul the series would never be finished.
