This season has had some pretty bad, if not outright amateurish writing. Telepetyr,
Admittedly silly, but a story telling necessity that viewers accept as part of the suspension of disbelief. I mean, you're watching a show with dragons, zombies, time travel possession, and resurrection and you are complaining about a guy traveling from point A to point B too quickly?
previously noble Northern houses conveniently turning evil,
I really don't get why people are so hung up on this. On the show, Roose Bolton was Robb's loyal, albeit cold, lieutenant. A meeting with Jamie at Harrenhall with some questionable dialogue was the only warning that he would betray Robb (assuming you've not read the books). Then he did just that. Do you want villains to sit around and sinisterly twirl their mustaches to coreograph whether they are "evil"?
Beyond that, I really think quite a few of you have missed the underlying message of the Ned Stark character...honor is stupid. Almost the entire point of the first book was that when it comes to one's own self-advancement, power, and protecting one's family, "honor" goes out the door and those who keep it are playing at a handicap.
Was Tyrion "evil" because he helped defend Joffrey's rule of Kings Landing? Is Jamie "evil"? The entire point of Martin's work is that these are often silly and arbitrary concepts. The northerners aren't behaving evilly. They see who has power and they are doing what it takes to advance themselves and protect their families.
Admittedly dumb, but again, it's TV. Jack Bauer can save the world after being shot through the stomach or infect with a biological weapon. Such is the nature of suspension of disbelief. It wasn't logical, but it's not the big deal fans are making it to me.
Dany killing a bunch of Mongol patriarchs and instantly becoming the new Khan (Klingon style)... but oh well.
But again, this makes sense and is consistent with the show's lore. Dothraki are a suspicious, primitive people. They saw Dany emerge from a huge pit of fire unscathed. To them she is a god. Of course it's not logical. That's the point. Dothraki aren't.
