I haven't watched the new season yet. I'm going through seasons 1-3 again in preparation. Previous seasons are fantastic, so I assume the new season will be too, but I can't give you a definite answer.
Sorry man, I missed that comment. Yes, it's on Amazon. lol ^^^
I just finished the season today. Great season but not as good as 2 or 3. It was a bit more predictable in how it played out. A lot of story retreads too. Luckily, I hear book 4 was mostly set up and the weakest of the series, so next season should be better.
