Unlike a lot of GoT fans, I didn’t have a problem with the plot of the last season. The problem I had was that they took about 4 seasons of 10 episodes each and crammed them into 1 season of 6 episodes. Season 8 wasn’t fully developed. It was more like a Cliff’s Notes of what the last several seasons of GoT should have been.
For 7 seasons they kept building the threat of the White Walkers. Then we get one battle and poof, they’re gone. Wait, what? That was it? That was the big showdown that we waited 8 seasons for? That should have been most of a season, not one episode. It should have been loss after loss, showing how unprepared everyone was for the threat that they had been warned about for years. It should have been an epic struggle for survival. And (IMHO) a few more major characters should have died.
Unlike a lot of GoT fans, I had no problem with Arya being the one to take out the Night King. If she didn’t do that, then what was her entire character arc for? Why did the show spend so much time making her into a badass if they weren’t going to do something with it? She needed to do something with her deadly skills, and with everyone expecting Jon to be the one to defeat the Night King, I think showing him getting hung up and not being able to get to where he needed to be was a good way to do it.
There needed to be at least an entire season dedicated to Dany’s descent into the Mad Queen. If we saw her slowly decaying, slowly withdrawing into herself as she loses ally after ally and friend after friend, then Varys having doubts about her would have made sense. Eventually Varys gets to the point where he loses faith, and then his turn against her makes sense. Instead, we got Varys turning traitor in basically one episode and then poof, he’s gone. Dracarys. The show was so rushed that we don’t even get any real time to se Dany’s hurt and betrayal at having one of her most trusted advisors turn against her. Dany’s descent into madness makes sense (to me at least), but not the way that they portrayed it.
With only 6 episodes I knew going into it that everything was just going to be rushed, so I just accepted that and tried to imagine what it would have been if they had taken the time to do it right. As a result, I actually did enjoy it, with one exception. Jon needed to sit on the throne at the end.
I haven’t read the books that House of the Dragon is based on, but from what I hear they aren’t as extensive and probably translate to about 3 or 4 seasons. I don’t know if they’ll try to stretch it out into a few more seasons than that, or if they’ll do other spinoff shows. I did read that George RR Martin is hoping that it becomes a franchise like Star Wars or the MCU Universe. I wouldn’t mind multiple shows of 3 or 4 seasons each, with each show focusing on a different part of the world or a different era.
