It's a little confusing at first, especially if you're not familiar with the story. The first few episodes jump back and forth between 2 or 3 different timelines. They all seem to converge by episode 5 or 6 tho (just started ep 6).
I'm really liking it so far, it's at least as good as I'd hoped it would be. I agree it's not another Game Of Thrones but I can't help but feel some similarities in its tone and fantasy elements. Could just be because they have a couple of GoT actors in it, too.
