The last episode was the best so far. Ironically Ned Stark had almost no screen time, despite him being my favourite character.
As for likeable characters, I think there's something to like and hate in every character of the series. It's just that one side prevails over the other. For example imho Ned is the most noble and good hearted character, but it's infuriating how he has absolutely no bite and lacks aggression when needed...
Whereas eventhough Cersei is the most evil character, I do understand her being terribly hurt by the fact that she was never loved by Robert. I also think it's quite normal for a mother to want the best for her son.
The only character in the series that totally baffles me is "Littlefinger". I just can't figure him out, every bit of him is so contrarian... truly well thought out character...
