We're all being humorous here about some serious shit --I happen to reside right across the PUGET SOUND from Max Boyce, for instance; so there must be something in the water up here, right, buddy?-- because irreverence is sometimes the only way to face a tragedy like the ruination of your favorite soap opera. Game of Thrones had always been such an ingenious and superior blend of tragicomic sex and swords and sorcery and politics and psychology, though. A baroque marriage of batshit brave heroism and batshit depraved villainy. Which is why, once the show carried on beyond the books, the seams started parting and the bloom fell off the thing and suddenly this season is a tragic travesty I can't quite cope with.
After years (literally YEARS) of painstakingly careful character development, they've all been given short shrift leading up to this apocalypse we all probably shoulda seen coming. Then again, I'm of the mind that MORE of our favorite characters should've died along the way on this epic highway to hell. So I dunno. This is why I, myself, am tragically only capable of writing beginnings and middles. The "ends" of stories don't interest me as much as the origin stories, I guess. For I'm one of the proud few who really liked how shows like The Sopranos and The Shield and The Wire "ended". As opposed to the way Breaking Bad ended, for instance. Although, I really liked how Breaking Bad ended, too. So go figure.
Which brings me to the big send-offs Kdot alluded to. The Starks were all murdered in spectacular fashion, Mance Rayder went out like a mensch, Ygritte like a boy-crazy dumbstruck lover, Drogo like a big dumb rapey badass, Ramsay Bolton like a rapey Napoleonic bastard, Oberyn Martell like a righteous moron, Olenna Tyrell like a boss, Hodor like a hero, Tywin Lannister on a toilet... The list goes on. So much of that death and destruction was EARNED, though. Up until this season, that is. To see the writers let the Night King be taken out like a clown by a little girl, Rhaegal the dragon taken out like an innocent bystander by a psycopathic clown, Brienne of Tarth taken out like a jilted rom-com mallrat by a redeemed asshole, and the once fierce but now feeble Cersei Lannister taken out like a lamb led to a slaughter by the very same, but suddenly irredeemable, asshole...
Well, fuckit. There's just too much to unpack. I think my grievance with Dany's heel turn is less severe. I saw it coming because they really did "show" it coming. For all this time, and if you think about it, the only thing that ever held the Khaleesi in check (and NOT go all burn-em-all bastshit crazy) were her trusted advisers. If it seemed like her descent into madness came too fast (kinda like Anakin Skywalker becoming Darth Vader came way too fast) it's because the writers messed up when they killed Rhaegal the way they did in the preceding episode. If they'd simply waited until THIS episode, the penultimate episode, to bring him down... Well, I would've wholeheartedly bought her genetically-compromised/God-complexed Targaryen pride overtaking her humanistic and pragmatic sensiblility. She'd already lost Drogo and Beric and Viserion, Jorah, and Missandei and then the romantic love and affection of Jon Snow on top of it. She'd been betrayed by Sansa and Varys, let down by Tyrion and the people of Westeros, and so... If one of Cersei's scorpions had killed her second to last "child" (as the people of King's Landing cheered as he fell from the sky) well, forget the "bells." That probably would have sufficed as a last straw back-snapping justification to go on a kill-crazy genocidal rampage.
(In the context of the show, that is. I'm not condoning indiscriminate mass murder, by any means.)
Easy narrative fix, in my mind, anyhow, but... Then again, what do I know? I'm sitting here, worn out by the whole thing already. And yet, despite my angst, I would still encourage the lot of y'all who have somehow managed to avoid this goddamned water-cooler soap opera for the past ten years to: GET IN ON IT!
For it's never too late to drink up, eat well, and be entertained. Nevermind the biting hangover... Game of Thrones, as it is and as a whole, is like a seven-course dinner-theater meal for the heart and mind. And well worth the bitter aftertaste. 
Cheers
