I plan on watching it soon. Looked amazing and I have literally not heard a bad thing about it.
What I can tell you is that the first two episodes of season 1 are a little slow. Mind you, I dont mean to detract you from it. But what I can say is that the end of episode 1 is phenomenal.
The show is pretty CGI based. Not heavily, but you can definitely notice it. But it's that which makes it pretty damn good.
As for the prequel, it's phenomenal so far. Not one episode I hate. Very excited for the season finale next week.
