It's OKAY. Nothing special, nothing super bad either, it's just okay.
They have deviated from the books a lot and have made unneeded changes. Where the books prevail in character development the show has drastically failed. Where the books took a lot of time building suspense and curiosity the show has done things at lightning speed leaving no time for curiosity or building any care for the characters. I don't care so much if they changed things and made it believable, it's just not believable. It had no depth like the books have, which is really unfortunate. Is it a good show? Not really. I watched dune and lord of the rings recently and was wowed at the character development and how slow paced and well written the scripts were. And my thought was wow, i wish wheel of time was done this well.
Its not a complete bust though, it has good bits, relatively okay actors and some good CGI.
For the amount of money put into this, it really shows that money isn't everything (is it mr potter?) Hahah.
Its definitely only a watch once kind of show, wouldn't want to go back and re-watch.
I hope they slow it down and actually make the script better by season 2.
