Arya's and Sansa's were quite interesting. At the time, I was not a fan of Sansa (oh, how times change) but the POVs from two very young, somewhat naive characters in a world so wrought with betrayal, their take on things were interesting. It preserved that sense of innocence in the first book, when the world was not unlike Robert - fat, lazy and ultimately unproductive, but safe. I really enjoyed Jon's POVs, more so than I did in future books. The Night's Watch was mystifying, and Jon's adjustment to this entirely new way of life was quite intriguing. I'm not proud of it, but on my first read I skipped a chapter or two from Bran. I just found his chapters dragged on for far, far longer than they needed to.
