The common thread from "all" the onesie-twosie reviews thus far say it's visually-stunning but weak on story. Expounding on that it seems the characters are dynamic and well-fleshed out but there's little need to root for them. Are the characters likable? The general consensus from the (counts on fingers) five?! early-reviewers suggest the actual "story" was left on the cutting room floor to make room for agendas and enviromental messaging. Take that however you will. Clearly more "miss" than "hit" if it's going for preach and pander.
BUT - imma watch it anyway. Still looks like a fun popcorn flik full of action and adventure. Will judge it on my own merits.
