Really quite good.

Rating: 8/10 (9 January 2010)

It's equal parts 'Dances with Wolves', Tarzan, Thundercats, Aliens, John Carter of Mars and lord knows what else-but that's great, they crib all the right places and know how to Use the sources wisely. The storyline serves a terric panoply of F/X, action, heart and drama.
You've prob. already seen this or read the reviews, don't have tons to add. Stephen Lang makes a great villain, Worthington and Uhura there carry off their roles well, Wes Studi and Ripley are welcome additions. I enjoyed the walker bots, the pterodactyl mounts, the hammer-headed rhinos and dayglo sentient plants. All fairly well drawn and realized by Cameron.
The baddies lose, the good guy turns and helps out the big bloo katpeople win and keep their planet. I think this will be a winner at Oscar time, I think there will be sequels, and I think it will hold up after repeated viewings.
***1/2 outta **** do see it.
