Bad stuff??? Like what? That show is virtually flawless!
Well, I am going to ignore that they don't follow the books very well. That's just adaptation.
But I draw the line at introducing new characters just for the sake of adding more violence and/or sex to the show. As if the books weren't already violent enough.
I can almost live with the changed names and appearances. Almost. The ages don't fit either (the Stark girls and Tommen for example) Some characters are barely recognizable for a reader of the books until someone tells you their names. Needlessly including token characters.
But the sword fights for example. In some parts the choreography is just dire. People cutting with swords that are only made for thrusting (looking at you Arya), people using ridiculous stances that would get them killed in no time (Brienne and Jamie, as well as Arthur Dayne, reportedly three very good sword fighters).
People using ranged weapons at completely moronic distances. Grrr.
Daenerys uses her dragons in the most moronic ways possible, getting them into danger needlessly, which causes one Dragon being shot down by a weapon that normally would have had no chance in ever hitting it (by the Lannister ballista) and causes the death of another one (the whole rescue action was executed so poorly it hurt).
"Plot Speed". this is infuriating to me. Lazy writing requires them to be completely inconsistent with people travelling distances. Especially in the latest season the main characters practically teleport.
There is a map of Westeros and the speeds at which people on foot, ships, and horses can travel are known. The writers/producers should use that information.
It becomes even more ridiculous if you plot on the map where they were going and which routes they had to take.
Moving a huge army across a continent without being noticed and so on.
The choice when to switch locations. The books are also doing that unfortunately.
The bullshit "previously on GoT" parts at the beginning of the show, always basically spoiling the surprises of the episode by showing the (sometines almost forgotten by the audience) characters that will play a role in the episode.
Argh it is hard to type all this on the mobile phone but I could go on for quite a while.
Oh and RE: the Mountain: he isn't _that_ one dimensional in the books.
