It’s very bad.
Martin has claimed he flew to HBO to convince them to do 10 seasons of 10 episodes instead of the 8 seasons with just 8 episodes in the final one [1]. It was straight up just D.B. Weiss and David Benioff call how the series ended.

You know there are two more episodes, right? That seems like an obvious finale reveal.
They just invent stuff that they have no idea how to explain later. Just like Lost.
There are also stupid leaps of faith like Holly's mom hobbling out of bed and sticking an oxygen tank in a clothes dryer(as if that would even do anything)...
