Being a fan of the books first and foremost, I think one issue with the show is it tends to put things to bed rather quickly. In the books, Robbs wife doesn't die, so there was speculation that she might be pregnant, and that we might be something happy out of all this. But instead, they both killed her in the show, as well as killed that theory for the books as well. Also, I honestly don't think there should have been so much killing of the folks at the wedding. Sure, in the books a lot of people died, but a lot were taken prisoner because they were mostly other lords, who make far better hostages than corpses .
That said, Great episode. Knowing what was happening didn't make it any easier for me, I had to pause and gird myself for what I knew was to come.
