Still can't decide to read the books or not and if I do, do I start from the beginning or just continue with book three after watching series two?
Season two has differed from the book quite a bit (not in a bad way), but the major plot points have (I'll assume after next week's finale) been hit. The story is so bleeding complicated though (and a few characters have been omitted) that I'm not sure what to recommend. I'd say, give the third book a shot after the second season ends. If you're not into after 100 pages...keep reading. That's how I was at the beginning of all of the books. If you're still not into it after 200, then you might want to start over.
