I don't really get how they hope to pull this off while remaining faithful to the source material. A significant portion of the central characters are very young children. IIRC, Brand is 6, his sisters are 8 and 10. Denerys is 12 or 13. Lots of problems here for the producers. They need good actors, they need to deal with the fact that they're going to keep growing up, and they need to deal with depicting children in such horrible situations. I think a lot readers disconnected themselves from just how young a character like Arya is when she goes through such disgusting ordeals. It'll be a lot harder to disconnect in a TV series.
