Alright, you lot of obstinate cunts. We all agree to suspend belief to a certain extent when watching GoT. We all know the premise is implausible, we know there are whitewalkers, dragons, hot blonde chicks that can't be burned, red priests and priestesses, etc. However, I think we can all agree that that is not a license to just throw random things in with no set up. We saw the set up for everything else. It all fit the story line. The massive chain coming from out of thin air, being pulled by skeletons that get smashed to bits with a single blow, after somehow being hooked to Viserion, is a stretch. The point is, there should have been just one scene of set up. Goddamn. You're all a bunch of GoT hipsters.
