The following is from TV Guide - Ask Matt section:

Question: Does negative reaction to Legend of the Seeker make a second season less likely? I know many fans of the book are harshly speaking out against the series, but I love the show. -- Maria O.

Matt Roush: The worst thing that could happen to a show like this is for it to be ignored by its fan base. The show did not get very positive reviews (including from me), and I'm not keeping up with fan reaction, positive or negative. But what will determine Seeker's future has all to do with business: how well it performs in syndication for the local stations and how well it sells in the overseas markets. I haven't seen any early returns yet, but Disney has made quite an investment with launching this new fantasy series into syndication, so I'd expect them to stick with it unless it proves to be an utter dud. But while I'm on the subject of TV fantasy, I wanted to revisit the topic of HBO's adaptation of George R.R. Martin's A Game of Thrones (the Song of Ice and Fire series). HBO has officially green-lit a pilot, based on a truly terrific (though currently still unfinished) series of novels. This is no guarantee the show will go to series, but it's a good sign.
