I thought episode 3 had some pretty shocking writing going on, but goddamn episode 4 gives it a run for its money. It's like the writers and producers settled on some epic fight sequences throughout the season and the rest of the scenes exist to shepherd characters between them and provide some vague semblance of justification for their actions.
1. How did Daenerys not spot a fleet of enemy ships with big black flags whilst high up in the sky on a dragon? Once the camera panned around it was pretty hard to miss. How can a fleet of ships ambush a dragon out at sea on a clear day?
2. Why didn't Cersei end the war then and there by having 4+ spear machines klap Daenerys in front of the castle gate? She was there with a pathetic army and the spear guns were mounted at short intervals on the wall and obviously powerful enough to shoot high up in the sky with hardly any deviation in their trajectory. Just one hit would turn her into soup. What's the dragon creeping in the back going to do when it wasn't even a match in the air? Cersei could send the Golden Company out the gate for good measure if the spear guns need to watch the dragon.
3. Where were all these surviving soldiers holding out during the previous episode? We saw everyone mowed down to the point of a few surviving heroes playing hide and seek in the castle.
4. All the stuff with Missandei was a joke. Jesus they're not even pretending to care about credible story telling at this point.
5. What was the point of the scene with Bronn? They didn't even flip him. He just talked s**t and left.
6. Tyrion has been reduced to a shadow of his former self with the new writers. He's literally been called stupid by the main characters for a while now. His monologue to Cersei had 0% chance of success and his old self would have sooner cut his dick off than look like a gormless moron in front of both leaders in the war. Cersei should have put us all out of our misery with Tyrion and at least had the spear machines terminate his painfully retarded existence.
7. The only person in this warped version of GoT who deserves the iron throne is Euron Greyjoy. He gets s**t done, can seemingly teleport his fleet anywhere, has balls of steel, puts his life on the line frequently, kills dragons before brunch and is probably the best hope of a coherent, powerful and long lasting ruler for Westeros. And he's actually entertaining.
