I'm not a fanboy, I'm not arsed about character arcs, I just want to watch entertaining TV, afterall, the writers own the characters and it is up to them to decide what happens. The issue I have had is that it has all become rushed and there has been some shit scenes.
I don't give a shit if it was a parley, Cersei would not pass up that opportunity to at least kill the last dragon, any commander would be aware that once the scorpions were known about, a way of exploiting their very obvious weaknesses would be found.
People can make as many excuses for how Euron hit the dragon, I was a great bit of TV for the surprise element as a viewer, but fuck off, its a scorpion, not a SAM or a Phoenix (fire and forget missile), it is basic shit, if you cannot see your target, then you cannot hit it and how the hell did Euron know what height and direction the dragon was flying from? Somehow he magically get the fleet in the exact channel he did and knew that they would fly past presenting an easy target and then gets a direct hit first shot.
Then the fight with Jaime, he manages to end up on the exact beach as Jaime at the same time?
