Debut was pretty fantastic, only problem is they have a lot to cover this year, so it felt kind of rushed with them going back and forth between 5+ characters. Was a Stannis fan from the books, and was impressed with how they nailed his character for the show. Of course Tyrion kills it again, expect a lot more greatness from him this season.
Should be easy for people to follow with Stannis being the only new main character for ACOK and this season, think there splittling the next book into to season which is def necessary as so much stuff happens in that book.
