1) This review is not getting into or about deviation from canonical material or trash-daptation knock down drag out fights going on around the world, in every language the original series was printed in books or narrated in, for audiobooks.
2) If the amount of money having been tossed around for the creation of this short series is accurate, then Mr Bezos may wish to have some deep forensic accounting performed and/or have an accounting of who and how so many people involved in the sausage making behind the scenes, got their positions. And I mean from top to bottom: writers, lighting, EDITING, all production and directing personnel, scenery/set design, clothing/armor, did I mention the WRITERS, and any and all "experts" on Renaissance Era technologies/armor/clothing/etc (yes, even if this particular world has gone from stone to space age, thousands of times before), CGI: either A) they are all from 1998 and brought not only their skill sets from that year when they time traveled, but also their PCs running Windows 98, OR B) they were not provided anywhere near the time in post production or instructions on what they were to create.
Casting: HUMANS: the casting department appears to have done a competent job in gathering a rainbow of skin colors in the British version of the CW evening soap opera actors they presented. I will for the benefit of the actors involved, assume they can all act very well. However, I have no way to confirm or deny this, based upon the pablum of idiocy(dialogue) they were forced to regurgitate on screen.
OGIER: this poor actor, it's not his fault. Not sure which is more atrocious: A) the brillo pads glued around his head and face. Where are his long dangling eyebrows, his super tall twitchable ears, both of which can convey depths of emotions with the slightest movement? And he's only 90 years old, barely a late teen, he can't grow a beard yet B) his super deep soul and open heart, he is to be a bright eyed babe in the world of men, innocent and open, where the sights of the Ogier Groves around the continent that have been clear cut, and the evil that men do to eachother, start to harden his heart and blunt his endless confidence. C) he's missing about 3 feet of height? If 6'1" Robbie Coltrane can effectively pull off 10 feet of height and over 4 feet of width on screen, almost 20 years ago, come on, what the heck?
C) WOLVES: one runty wolf and the back sides of German Shepherds & Belgian Malinois. What the heck? Is there a wolf shortage?
All around its bad. Very, very bad. Plot holes and contradictions the size of the Grand Canyon, sometimes in the same episode, sometimes just seconds apart. Did no one screen test this farce in front of test audiences?
