4. Yara Greyjoy
From the moment Yara rode up on her horse and Theon unwittingly started finger-banging his own sister, I couldn't shake the sinking feeling in my gut about Yara. First of all, in the books she's named Asha, so to some extent, I can almost just write her off as she isn't the same character. Asha is hard enough to eat guts for breakfast and ask for more. Yara talks a bit big talk but hasn't done a single thing to prove herself as fierce warrior as yet. Moreover, what other sex drive Asha has in the books (and it's quite expansive) is entirely devoid in the show where she's basically a man in drag. Asha is described as lean and long-legged, with short black hair and a sharp nose in a thin face. On the show, she's squat, flat-faced and dirty blonde. No offence to Gemma Whelan, who plays Yara on the show, but the sex appeal just ain't there, nor is the Ripley-esque aspect that's so crucial to her character. The reason this is so disconcerting is as the story progresses, Asha's (or Yara's) role increases significantly. Here's hoping in the coming seasons we get to see Asha griding her axe, hacking limbs and cracking skulls - and maybe bumping in the trunk a little bit too.
