I'm hoping it's better than the Wheel of time they are doing. Although I do like the wheel of time series, I just don't like some of the libertys they take. Watching the clip kinda looked like the characters were too CGI for me but I hope I am wrong.
Hopefully they've employed better actors than the production team for The Wheel of Time did. That cast is largely terrible with only a couple of the actors doing a credible job.
I'm wondering if (or how much of) it's based on material from The Silmarillion. I've always thought someone ought to try to make a coherent story out of all that history and lore, but what a task.
