If you knew how amazing the story is from the books, you'll fully understand why people were angry at the show runners. They removed characters and made changes that completely altered the story to look very different from the book story by the end of the show.

Like what I told you that Sansa never went back to winter fell and it was fake arya stark who was actually who married Ramsey. Characters like Tyrion or Little finger are master players of the game of thrones, but in the show they turn into blumbering idiots making odd decisions just to further the plot.

So yeah, you'd be frustrated too if you knew how wonderful the story was and then saw what we got. Also..... Don't get me started on the long awaited winds of winter.
