Yeah it was an underwhelming season finale. Part of me thought I was watching like a season opener at one point, barring Arya/Hound being awesome and Ygritte shooting Jon. Sad we're gonna have to wait another year for
Lady Stoneheart
, but it will only make it that much more of a shock. It really feels like they saved the best parts of book 3 for the upcoming season (except for the Red Wedding ofc).
The highlights of this season for me were Dany's Dracarys scene, Tyrion/Sansa wedding, Red Wedding and the Queen of Thorns. There's plenty of this sort of amazing stuff to come for season 4, don't think it will have a lot of slower episodes like this season had, if any.
