It's a GRAND story arc. We haven't seen the end, with the books yet. I firmly believe that it will have a bitter sweet type of ending. There will be sacrifices made but I do think it will end on an upbeat note. What makes Game of Thrones so great is the character arcs. Game of Thrones and Dexter are at completely opposite ends of the spectrum there. Every character in Game of Thrones is well written, is interesting and you just love to see what happens next. With Dexter, I couldn't give two craps about any of the supporting characters after eight seasons. As far as the Others go, I wouldn't be surprised if we get a point of view chapter from an Other at some point. That said, he needs to cut some of the fat out of the series and get to the goodies.
