I’m also waiting for the entire script. Whoever is posting these is cherry picking them and I think reading the complete script is the only way to know what kind of quality writing it is.

As for the concept art, look how far things changed for the other movies. Nothing would have looked exactly like the concept art. As cool as it is, it would have been further adapted and altered to get to the final look. This story has some neat concepts, but a few neat concepts, scenes, and art does not make this a better story.
