IF they had used different characters rather than those named in the original story (to follow a different narrative) it wouldn't have been so bad, especially if they wanted to tick more diversity and equality boxes. To use some of the same characters and introduce other weaker ones and to deviate from a well-known plot invites holes and criticisms. To then omit key events and introduce irrelevancies is then an insult to those who may watch a series because of prior interest, by Episode 3 it looked like they'd blown most of the CGI budget when there were events we would want to see. What's wrong with using a straightforward linear timeline instead of introducing a disjointed future? The trailers made it look promising but it ended up disappointing me.
