I am surprised it took me this long to find out about it:
You have no idea how pumped I am for this.
The Sword of Shannara was the first fantasy book I ever read, and really led me to be the nerd I am today. While I know many think the series is meh and just a Lotr copy, I still love them. The trailer looks really well done, too.
It looks like they are setting it during Elfstones of Shannara. First episode is on January 5th.
