It might be a stretch, but it feels bizarre that it seems to have turned into a men vs. women kind of thing. But then again, everything about Dorne in this show is bizarre. Killing Trystane, for example - first, how the fuck did two of the Sand Snakes manage to teleport to Winterfell to kill him, and second, why bother? What does killing him actually accomplish for them? Wasn't the whole point of this stupid subplot that they wanted to retaliate against the Lannisters for Oberyn's death?* Because now it seems like it's just a regular old coup, one executed (no pun intended) in a very crude, blunt manner. It doesn't help that Doran and Hotah are both very well-liked characters in the books, and Alexander Siddig proved that he had the potential to be a fantastic Doran in his brief screen time last season - making it all the worse when the two of them were so lamely killed off. Also, why do the opening credits keep referring to the Water Gardens as Dorne? I know, I know, this is the geekiest complaint ever, but it bugs me because it's not consistent. Everywhere else is referred to by the name of the city or castle, not the entire region. Are they worried about confusing us? At the very least, they could just call it Sunspear, which isn't entirely accurate in the books, but it's close enough for the purposes of the show.
*Not that Oberyn would have approved of this plot. As he very pointedly said once, they don't murder little girls in Dorne.
