Excellent fantasy drama that developed very good characters that you felt for and cared about. They offed several prominent characters throughout the season to keep you on your toes, assuming you havn't read the novel as I hadn't. It seemed like every time I was thinking, They Rock!, they ended up dying soon.
Overall, my biggest gripe was the Fellowship Of The Ring style ending. All of season 1 seems merely like a buildup for the remaining seasons rather than a stand alone season. I'm not really a fan of that.
As for the future. With Eva Green off that Matturd Camelot, she can finally fill the role she was destined for in Melisandre
Mark Strong would be a great choice for Lord Stannis.
