People keep saying it was rushed but I the opposite would have had people moaning that it was too drawn out.
Take the Battle of Winterfell for example, people say that was rushed and anticlimactic but how else could that it have gone down? It could have only gone one of two ways, either the Knight King wipes everyone out or he himself and his army are wiped out. Don't forget the Knight King got his 'mini win' over the heroes in Season 7 when he took out the dragon so I think people are guilty of viewing/rating Season 8 in isolation rather that how it fits the entire story all the way through seasons 1-8 (I guarantee if you watch all 8 seasons back to back no one will be complaining about those final 6 odd hours being rushed then)
I was thinking about the ending last night and was actually struggling to find anything prior to GOT that had an ending as good as the rest, take my favourite films of all time Batman Begins and The Dark Knight - the final piece of that trilogy is The Dark Knight Rises and that's awful. The Alien films, they all went down hill after Aliens. The Terminator films, they all went down hill after T2. The ending of The Lord of the Rings trilogy I find a very similar long goodbye like the end of GOT was last night. If you take TV shows then look at how crap the likes of Lost was at the end. The Big Bang Theory while a completely different type of show to GOT has barely raised a smile with me this last season. When something has been so good for so long it seems history tells us it's very hard to end said thing at the same level that everything before it had maintained
Even if the ending wasn't necessarily what I would have wanted I look back on Season 8 and other than episode 1 it had me on the edge of my seat every single episode so for me that means it was damn good TV
