I won't post spoilers, in case you don't watch it, aren't caught up, or didn't get a chance to watch last night's episode yet. All I can say is that I thought most of the story lines were wrapped up brilliantly (if I can use "wrapped up" to describe this show). What's so great about this show? It's brutal as all get-out, it's graphic, and it's unpredictable -- meaning don't get attached to any one character, because there is no guarantee any character, even the most heroic, even the most likable, will survive a season.
What's so great about Game of Thrones is the character building and the conflict. It's compelling. You are drawn into this world and can't look away. Some of the relationships make you cheer. Some make you cringe. But the characters are all flawed and fascinating. It's brilliant television....and I can't believe I have to wait almost a year for Season 6!
