Overall: Generic and boring modern fantasy show, atrocious adaption. Ruined what could have been great as there is enough source material for 10 seasons.
The Show: As a TV show in itself, it's another fantasy show. The showrunners have made it into yet another of the plethora of similar shows, however more poorly made than others. The sets look cheap, like Dr Who sets, e.g. the White Tower is supposed to be majestic and ancient, they make it look like the sets of Blackadder. If I was Jeff Bezos I'd be demanding to see where my 10m dollars per episode went - I'd be calling in the forensic accountants.
For some reason there appears to be a lot of bots leaving positive reviews, all sounding the same.
As an Adaption: Where do I start - in fact, don't rely on me for information, feel free to search the hundreds of youtube videos and forums trashing the adaption. Briefly, the showrunners completely misunderstood the story, or simply didn't care. The books have a massive following due to the charm of the story, there is the battle of the sexes, clash of cultures with amusing consequences, action, mystery etc.
The show completely misses all of this. Two examples: first, it starts in an isolated village where few people have visited in hundreds of years and so everybody looks the same except for one person who looks different - this is a major plotline of the early story of why he looks different, however the show has the village looking like New York City with a mix of people from everywhere - completely misses the point. Second, one of the main characters, Matt, is a charming rogue in the books, but in the show they just have him as a dishonourable thief (in fact I think they mixed him up with Jimmy the Hand from the Feist books).
Final example: Although I only got to Ep 2 of Season 2 before I couldn't watch any more, I did see a youtube video of the Battle of Falme (finale of Season 2), in the books this is a huge battle with resurrected heroes in a mist, the show appears to have made it into a dozen people dressed for a cosplay event.
Casting: Not great, some act ok but nothing brilliant. The best cast member left after the first season. Rosamund Pike is annoying when she pulls her stupid faces trying to look mysterious. Most of the female actors appear to have been made to look quite masculine.
My background: Have read the books.
