Well, I thought it was a pretty decent finale... yes, we can nitpick about certain points (Jon standing a few feet away from a jet of flame hot enough to melt iron? Surely that would have taken off most of his curly locks and left him a bit crispy around the edges?)...
And of course we all saw Jon killing Dany coming. I never thought much of Emilia Clarke and Kit Harrington as actors, but they both played a blinder in the last couple of episodes. And Dany's story is probably the most tragic in GOT. I'm going to cut and paste a bit from The Guardian's review because I can't put it any better and I don't want to rewrite it to try and sound more clever than I actually am...
A girl raised on stories and dreams who survived tragedy and birthed three dragons from her dead husband’s fire. It’s the story of how that girl became a woman who believed that she alone could change the world, but who never realised that what she was really proposing was razing it to dust and ashes. Who never grasped that it’s not enough to say you are good and expect everyone to join your cause, or that liberation and conquering are two sides of the same coin. And who, most importantly, never understood that Westeros was not really hers but a half-glimpsed dream of what might have been. 
As Anna said, I'm totally OK with the surviving Stark kids getting somewhat happy endings! In fact, I was surprised about how funny this episode sometimes was! Not least the bits where Sam tried to bring democracy to Westeros, Edmure learning precisely ****-all over the whole of the series, Davos exasperatedly saying 'not sure if I get a vote but...' and that final meeting of the council where, after all the death and destruction, it resorts to silly bickering around a table...

So GOT is over, let's hope the multiple proposed spin-off series might transpire and be something like as good. As Pol said, it's an odd thing when something as silly as a TV show leaves you feeling a bit saddened but when you've been really enjoying something for nine years, surely it's only natural to feel a bit bereft?
Oh, and apparently the online poll from those fuckin' over-entitled
idiots who DEMAND a remake of this season is up to a million and a half of these losers, I would dearly love the makers of GOT to post something like...
'Hi, Game Of Thrones 'fans'...
Nope. Get the f uck over yourselves. You didn't like it, suck it up, buttercup. Tens of millions of $$$s will not be spent because something didn't meet your expectations. I mean, did you actually think that it would happen? What in the actual F UCK is wrong with you?
Yours sincerely, everyone here at Game Of Thrones. xx'
