So here's the thing, I'm more of a reader of the series. I've only watched the first couple of episodes of the show, but I never continued because something about it felt off. Maybe it was the actors not resembling how I pictured the characters, or maybe it was them pronouncing words differently (Catelyn being a notable example), but in any case I thought the show was an interesting companion to the books, though I much preferred the books. That said, I knew that the show was probably going to be the only taste of any sort of ending to the story given that Martin's probably never going to finish those books.
This is honestly the biggest wet fart of an ending I can think to a story as grand as Game of Thrones. The way Dany was killed just feels wrong to me. Like the show spent literal years building up her attempt to reclaim the Iron Throne, but then she's killed by Jon. If you really have to kill Dany, then maybe do something less anti-climactic. Like the way she's killed doesn't even justify 8 years of character and plot development. I'd have hoped for her to go out in a blaze of glory (pun not intended).
And Bran being king is the stupidest fucking thing ever. Bran was always one of the least interesting characters in the book in my eyes, about the only interesting thing was how he got crippled which showed early on that no one was really safe. That said, him becoming king is a direction that absolutely makes no sense. He's a crippled kid/guy (however the fuck old he's supposed to be now) that becomes a psychic after his home is sacked. It's like, would you ever guess that this kid would be king at the end of it all? It's not even clever in a "subverting your expectations" kind of way, it's just plain stupid.
Looking at all this, it's insane how botched this was. I've been hearing that the show went downhill after they ran out of book to adapt, and frankly I'm sort of glad I never hopped on the show. At the same time, this is about the only real ending I'm ever going to get, which sucks.
