The characters were whitewashed, and the overall casting of the lead characters felt wrong to many. What disappointed fans in the adaptation were big deviations from the books (characters, plot lines, tone). Some feel the show tries to be more “dramatic TV” than thoughtful sci-fi, perhaps diluting complex themes so it appeals to more. It’s a complex and richly detailed fantasy world where many interwoven plot lines build up over thousands of pages. Fans say the TV adaptation frustratingly fails because it drifts away from the source in many big ways.
