The remainder of George R.R. Martin's third book, A Storm of Swords, still remains a treasure trove of trauma. Season 4 lacked assured direction and had some big omissions, but it made up for it in some really compelling arcs for Arya, Sansa, Tyrion, and Jon Snow . Bran may have vanished halfway through the season, but he appeared right at the end to raise the stakes. With no more war, and no Stark (or Baratheon) soldiers actively battling Lannisters, everything now becomes about each characters' individual journey.
The Blu-ray set had great behind the scenes extras, histories and lore, and a documentary special on Episode 9, “The Watchers on the Wall”. My favorite extra “The Fallen: A Roundtable,” is a special where Game of Thrones writer Bryan Cogman gathered together most of the actors who died this season and had them talk about their experience on the show.
DEFINITELY GET THE BLU-RAY EDITION.
