As someone who has watched Game of Thones (and someone who has watched an ungodly amount of terrible anime) this is so on point it's unbelievable.
This is pretty much every Shonen Jump animation (Naruto/Bleach/Dragon Ball) ever. I've watched a million of these intros and these guys have nailed it.
(I also spat out my water when Joffrey appeared looking like a slimy cheeseball anime villain.)
The music is particularly good. I would watch the shit out of this.
