Nothing much new is shown in this Game of Thrones Season 6 teaser trailer. In fact, I'm not sure they show any new footage at all.
But there is a super cool voiceover, and it's going pretty meta.
"They have no idea what's going to happen," says Bran Stark, at the end of the trailer. Who are they talking about -- the audience or the show's producers? Either way, it's a clear reference to the fact that, for the first time, the show is fully extending its reach beyond the book since George RR Martin is being way too slack in finishing the books.
I think for the most part people agree that Season 5 was one of the weaker seasons of Game of Thrones so far, but I'm still invested. And I still want to see what happens next. I'm keen.
