I'm a bit skeptical that with this film, they seem to have lost a lot of the moral complexity that made Dawn so engaging. There were no real villains on either side in that film, no "good" side or "bad" side to root for...even Gary Oldman's character was very sympathetic. As a result, I really felt that helped make things so much more interesting and suspenseful.
But in this film, the humans seem to be standing much more firmly on the side of evil, with the sides being more clearly drawn. "To save humanity we must abandon our humanity". I get that they're telling a different story here, but from what we've seen, it seems to be a much more generic tale than the previous two films.
