So, I finally saw the episode last night and well...it wasn't that bad. Like, let's make petition to redo the whole thing bad, lol.
I enjoyed it more than episodes 3 and 4, because I felt like the story lines / character arcs this one ended had at least somewhat satisfactory conclusions (when compared to ep. 3 and 4) and I didn't register that much of the usual dumbness (like stealth fleets with sniper ballistae or characters using fast travel) that has been an issue with the show in the last seasons. And it did look and sound gorgeous many times.
I have no issues with Mad Dany. I get it could have used a bit more time, but she has had her whole self image built on her being the rightful ruler, loved by The People and the mother of dragonS. All these save for one dragon has been stripped away and she defaulted to the ways of every other dictator (and she always was one) whom the The People just don't understand.
(Haven't read the books btw)
