10. Game of Thrones

The Sand Snakes arc in "Game of Thrones" could have been something great, but instead it was filled with bad dialogue and plot, which is probably why they axed the plot so clumsily in season six. They took such a diverse part of Westeros and made it completely and utterly stupid. And the fact that they wasted Alexander Siddig (Prince Doran) in that role and didn't even let him do his great monologue from the books is just sad. But the part that really gets me is how Oberyn said that "Dorne doesn't hurt little girls." It's true. In the books, Dorne values women---they are equal to men---and operate on a different, often better moral system than the rest of Westeros. It was a snipe at the Lannisters. A way of telling them that they wouldn't harm a girl entrusted to their care, a girl who is by all counts innocent. But what did the show do? They killed Myrcella cause they gotta shock the audience.
