So with ONE EPISODE LEFT, a report card on what Seasons 7-8 did with every major character....
Cersei Lannister: After 6 seasons of Cersei being a generally despicable character doing generally interesting things, even some smart things such as getting the jump on Ned and obliterating her enemies in the Sept, in Seasons 7-8 Cersei does.... almost nothing. She does do the smart thing of betraying her enemies in The Great War, but otherwise when she’s not banging Ueron Greyjoy she spends most of her screentime smirking at a balcony before ultimately creeping down to the basement of the Red Keep to be buried. Huh.
Jamie Lannister: After 6 amazing seasons wherein we watched Jamie transform from a despicable monster who literally pushed a kid out the window and murdered his cousin to get back to sleeping with his twin sister, to a conflicted but honorable man who aided Brienne in helping the Stark girls, Seasons 7-8 see him abandon Cersei to do the right thing, do right by Brienne, only to.... abandon Brienne and rather than return to KL to stop Cersei he tries to escape with her only to be buried under the Red Keep. Huh.
Tyrion Lannister: After 6 seasons of Tyrion generally being the best character in the show, Seasons 7-8 relegate Jim to a supporting character and he generally ranges from sucky to boring.
Dany Targ: After 6 seasons where she rises from being sold to a warlord to amassing an army and three dragons to cross the narrow sea to reclaim her throne.... in Seasons 7-8 she makes one stupid decision after another and then suddenly goes crazy and firebombs the civilians of KL for no reason whatsoever. Huh.
Jon Snow: After 6 seasons where he rises from a bastard son of Ned Stark to Lord Commander to King in the North, where the dude is literally killed and resurrected.... in Seasons 7-8 it’s finally revealed that he is the Song of Ice and Fire - the trueborn son of Targ and Stark and rightful heir to the Iron Throne. And then he basically does jack crap against the Night King, jack crap in the battle of KL, and generally sulks and claims allegiance to Dany.
Sansa Stark: She gets way too much screentime being a dumbass in Season 7-8, but to be fair that was par for the course over the entire series.
Arya Stark: Spends the first six seasons honing her craft and nursing her grudge against Cersei and then.... in Season 7-8 she jumps out of nowhere to kill the Night King and then does absolutely nothing against Cersei.
Bran Stark: Become the 3ER who can see anything in the past and control other people and animals and has some connection to the Night King and then... in Seasons 7-8 he provides some flashbacks to further the plot and then does absolutely nothing against the Night King except sit under a tree as bait because the Night King “wants to snuff out our memories.”
White Walkers: Really, I don’t need to go into this again.
Hey - they at least got Cleganbowl right!
