I binged most of season four yesterday and in comparison, the season five opener was somewhat of a letdown. They lost a lot of good talent with the demise of Tywin, the Hound, Lysa Arryn, and Joffery. We need some new "bad guys". Really going to miss Tywin though. Those scenes where Arya was his personal servant were some of the best.
Dany needs to get tough with those dragons or they'll walk all over her. She's kind of a hot mess right now. If it wasn't for the sneaky Red Woman, I'd back Stannis all the way. She (Melissandre) has that way of talking that really rustles my jimmies. The actress really pulls it off.
