Nothing surprising but I was expecting a longer and more intense fight, not very satisfied though tbh.
All my GoT experience can be summed as "not very satisfied tho tbh" anyway 
Nothing is ever going to equal what you can visualize in your head as you read. To really do the books justice it would've had to be some insane 12 movie series each with the budget of a LOTR production. The TV show has done extremely well with what they had imo, and it's the only realistic way the novels were ever going to be portrayed on screen. As far as adaptations go they've been doing allright. And by allright I mean critical and popular acclaim.
Like a lot of people I read the book years ago so all the little changes and additions seem like superfluous bullshit. I grudgingly agree with Xant that it's mostly a "hipster" type thing though. A completely undeserved sense of ownership over some piece of culture just because you've known about it for longer. The fat fuck himself greenlighted the show and wrote a few episodes, and editorializes the rest. There might be separate "canon" between the tv show and the book, but that's also due to the nature of the medium. A TV show is a collaborative process, the actors alone can add a whole facet to a character, not to mention the other producers and writers all having their own styles with strengths and weaknesses. And of course the physical and budgetary limitations.
TL;DR: just accept it's not a perfect adaptation of the books and enjoy it for what it is.
