This has to be the best political thriller series I've ever watched, and I've watched hundreds of TV series. Nail-biting, suspenseful and I had to concentrate to keep track of the nuts and bolts of the plot, which kept me thoroughly engaged for eight hours. Pity season/series 2 isn't out yet.
At first I only saw Robb Stark, but it only took the first few minutes of the first episode for that to dissipate because Richard Madden transformed into a totally different character.
