Ya I still haven't been able to go back and do a rewatch yet.
I tried once last year, got into the 2nd season and couldn't do it. Knowing where it was all ultimately heading.
I was honestly pretty satisfied with the show right up until The Longest Night episode in season 8. Ya the writing quality had declined a little in season 7, and the pacing issues were there... But I still enjoyed that season a lot.
But the way The Night King was killed in one episode, one battle, and killed so easily by one person... That did not sit well with me at all and the rest of the season just completely fell off a cliff after that.
It sucks because I really think you can see where a potentially great ending was headed.
If they had done it the right way, season 7 deals entirely with Danerys first attacks on Cersei and her Army, and those events and fights get spread out over an entire 10 episode season 7.
Season 8 deals with Danerys and The Night King, the Night King getting his Ice Dragon, and then Danerys going to Kings Landing for a truce to fight The Night King. Again over a full 10 episode season that helps deal with the pacing issues and leaves more room for quality character development and writing
Then Season 9 is an all out war across 10 episodes between The Night King and the Living. You can spend ~3 episodes building up The Night Kings march further South towards Winterfell, and then a ~3-4 episode long war between the Living and the Dead. It doesn't have to be a fight solely at Winterfell. At one point in the battle the Living could lose Winterfell and have to retreat south, before ultimately winning the battle. Then the final episode or two of the 9th season focuses on the aftermath and loss of Battle.
Finally, season 10 deals with the fight for Kings Landing, Danerys going mad, etc. Etc.
It was set up perfect IMO to be a 100 episode, 10 season long work of art, hands down the greatest show of all time, talked about for years and years later....
Instead, it just completely fell apart in 6 rushed episodes.
