It had potential, but I actually thought the production quality was sophomoric and the special effects budget was next to nothing. They seem to have spent a lot of money on casting, set pieces and wardrobe, but the special effects are cringeworthy, about what I'd expect from a WB show from the 1990's.
As many have said, the timeline-jumping made the story unnecessarily difficult to follow and didn't make any sense, even if the book was written that way (don't know, haven't read it...although my wife did so she tried to keep me up to speed as best she could). The fight choreography is reasonably well-done. But I must admit, the Bard character is flat-out awful and doesn't even help advance the storyline IMO.
I'll stick with it for season 2, but on the whole I thought season 1 was a disappointment.
