I want too to rewatch the series with the proper insight, but I have so much new stuff to watch that I consider unlikely to find some proper time to sit down through everything again. But it would be quite a rewarding experience to watch it to appreciate more the story and all the nuances, and be prepared for the shocking deahs (speaking of that, I don't think I want to watch the Red Wedding or Oberyn's death ever again. I watched on YouTube the fight between the Viper and the Mountain but I always stop before Gregor Clegane tackles him to the ground)
(Speaking of this now... I remember vividly in the battle there was a scene where Oberyn was grounded like that and simply rolled away quickly, couldn't he just do it again? yeah, I know, the surprise, he was caught off guard, but DAMN
)
