My 2 bobs worth.
I could be in quite a unique position here. I watched season one before listening to the audio books. That's the 1st edition of the audio books narrated by Kate Reading, Michael Kramer. Not the new release narrated by Rosamund Pike. I quite enjoyed the 1st season. Then I listened to the audio books. WOW the books are excellent, engaging and captivating and to my annoyance the series deviates from the books from the very first episode and NOT in a good way. Why the script writers even felt a need to alter some of the main characters character is beyond me !
Mat is unrecognisable in the series, in the books he is one of my favourite characters, Perrin is single until something like book 4. In the series he is married from the get go to some invented character. It goes on and on.
As a producer it is easy to see how Rosamund Pike got one of the major roles, that and the fact that she is a excellent actress, BUT like several of the other characters she is physically incorrect. In the books Moiraine is a tiny woman, short for good reason. It is her personality her force of will that commands the respect and obedience she receives from many others throughout the books.
Lan is supposed to be a big man and I mean Alan Ritchson type big (Reacher TV series). Daniel Henney plays the part quite well but again is not physically correct and not the character from the books.
Hammed Animashaun plays Loial an Oger (pronounced O'gear) a true giant of a being around 2.5 metres tall. The actor does a very good job and Loial, so far, appears to be one of VERY few characters that have remained truer to the books. Why he is not afforded even the simpler effects given to Robbie Coltrane in Harry Potter is again a clear indication that the producers are only paying lip service to the books.
So several characters are physically incorrect, these are not the only ones, don't get me started on "ageless faces" either, that's not the only issue with the series.
Piss pore casting! Is probably the biggest issue, not just mismatched physical characteristics, but horrible performances as well. Strangely the casting of the side characters appears to quite good sadly the main characters are way off. 2 excellent performances are Zoe robins and Rosamund Pike, if only Rosamund was 160cm or less, tall. Zoe plays Nynaeve al'Meara and puts in a stellar performance as the village Wisdom out to save her friends from the evil of the White Tower and it's occupants.
Notable performances by Sophie Okonedo, Michael McElhatton, Kate Fleetwood (who plays a VERY unlikable character) also these characters are supposed to play a much larger role further into the story. Who knows what the morons at the helm of the series will do next to destroy what is an awesome story if they would leave it alone and simply follow the books more closely. Unfortunately for Barney Harris and Marcus Rutherford the characters they play are so distorted, destroyed, so far off the characters from the books that it is impossible, for me at least, to give an honest account of their performances. I state categorically that the two worst casting choices are Madeleine Madden (Egwene) and Josha Stradowski (Rand). These two are so wrong for the parts it's indescribable. It's hard to tell from this series if these two young actors know their craft or not, as they are just not suitable for these roles.
What on earth gave the writers/producers the, now proven, unfounded, moronic, cataclysmically arrogant idea they could write a better story than the author (the late Robert Jordan). The stupidity behind the concept of changing anything from the book to make the series is immeasurable.
The one clearly identifiable result of this the first season is that every single person responsible for casting and writing this show should be herded together and dropped in the middle of "The Blight", they are clearly under the dark ones control and out to destroy the world of "The Wheel of Time".
The producers, writers and casting agents are proof positive that public floggings should be returned.
This series should have been the next biggest thing since Game of Thrones! Instead it's mediocrity will leave it as simply mediocre, not that it actually rates that high.
The simple fact is before I knew how much the series was destroying a great story I quite enjoyed, despite some cringe worthy performances, and WAS looking forward to the second season. If you have not read the books yet then you will probably enjoy the series. If have read/listened to the books you will probably have to do what I am doing, watch the series calling it something else in your head. This series is simply NOT "The Wheel of Time". I highly recommend the Audio Books narrated by Kate Reading and Michael Kramer. I am currently listening to all 14 books for the second time having listened to them for the first time early last year. Currently half way through book 4.
