If you've never read the book series made famous by Terry Goodkind, then you're probably better off. This show takes very little from the original story, but adds much more to make it worth watching. The acting is superb, the new story is very well done, and the overall show is top notch. Terry Goodkind gave his seal of approval to this show, and I do also. Unfortunately, only 4 audio commentaries are offered, so if you want to learn more about the underneaths of the story, you're out of luck here (however, the four that were done are VERY well done, and include the two main characters.) Some other smaller featurettes about the show are included on the last disc.
Overall, if you haven't seen this before, it's definitely worth a watch. If you followed it on syndication last year, there's nothing new unless you enjoy commentary. But it's definitely worth watching again and again. Be prepared for the new season start November 7th!
