From the story telling perspective and things like the Jon/Arya reunion, Jon riding the dragon, Jon finding out his true heritage, Jaime arriving and the first thing he sees is Bran, Sansa/Tyrion and Sansa's overall reaction to it all, Arya/Gendry and even Theon rescuing his sister and thus getting the upperhand on Cersei's greatest ally, these were all things fans have long anticipated. The fighting will likely start in the last half of the next episode and lead into the epic battle episode in week 3. Some good one liners and shit in the first, I thought it was a good setup episode.
