Honestly I thought episode 6 was one of the worst, if not the worst episodes of the entire series. The whole episode was pretty shit and the decisions in how they're taking the main story is starting to stink of the same old cheesy OTT heroic formulas, as you can see in your usual American TV series shitbag, like "The 100". The main story took a massive turn for the worst in this one episode alone in my opinion ( yes, my opinion, I will not assume many or all will share it ). The whole episode was just silly, had a bunch of pointless bullshit between Arya and Sansa that could have been condensed into less scenes and the whole heroic party adventure beyond the wall just seemed retarded as a whole, as well as how it all ended. The very ending of the episode was predictable and I expected it to happen at some point, but the way they went about it was shitty. It's left a bad taste in my mouth, what they chose to do with the main story arc was dogshit and to top it off, it was badly executed. I am not going to write much more about it as I don't really want to touch on any spoilers, just don't get your hopes up for a quality, well executed episode.
