I think it’s quite problematic that we already know basically all of the good guy main characters are in zero danger. There are some new characters, but none have a strong enough characterisation to really make me care about what happens to them. They can spend as much money on the big battle set pieces as they want, but without any real stakes these just feel like boring CGI padding to drag the story out and milk the audience for more money. This show has nowhere near enough depth to justify five seasons.
