I watched that and felt somewhat disappointed. Not merely because of the last episode but because of the direction the series has gone in. I mean, GoT is a very good show and will be regardless of what happened in season 6/7 or will happen in season 8. But I've developed a few issues with the show that keep me from genuinely loving it now (and over the last 3 seasons, I guess).
For one, the "main" characters are all too weak. They're all fairly bland, can't really act and pale in comparison to the strong supporting cast. The ones who aren't so (Cersie and Jaimie) are complete shitbags one of which has been given far too much importance/master tacticianness. Tyrion has over the seasons become more and more irrelevant. I've always felt that while killing off important characters made a big impact, I thought it left big vacuum both in terms of the story as well as the personalities you were watching. Short term impact but long term loss IMO.
The other is that essentially game of thrones has gone from being fantastic, gritty and deep show, to what now really resembles a Hollywood blockbuster dressed in top quality drama clothing. It's still very good just nothing special anymore.
As for the last episode, like episode 6, the writing is just average. The whole dragon pit scene was extremely clumsy and showy, and had very little depth. I've seen the term fan-fiction being said about this season a lot. And it's bang on the money. There's a lot of punchlines in place of good dialogue. A lot of unions that are supposed to make you make fans go 'yaay'. A lot of last minute saves that entire scenes are set up merely to ensure happen so that a main character survives/looks good. And then there's a predictability. Most people knew (almost) John's heritage. And did we need to see the marriage happen to show us the genuineness of the parents relationship? The Little Finger shit was predictable and people saw it coming 5 episodes ago.
All of the above is fine because it wont change that it's an excellent show that I will always watch. It just reduces the level a good notch or two.
