Banned for the monkeys I'm sure had war.
My issue is that it's not really well made from a story or technical point of view.
Humans can travel to other planets, but we don't just come back and kick ass or nuke it from orbit.
The military engagements were amazingly sloppy, especially for someone who did an okay job with Aliens. The big plane was so slow and had open sandbag positions. That makes no sense. The walking machines were cool, but cumbersome and barely armored. Why use unarmored infantry where breathing is such an issue? The lines were too spread out.
Why are we going to drop a large amount of explosives strapped to pallets on some shrine of theirs when A) A small nuke would do, and
the deposit of material is under the tree we burnt down, not the shrine dealy. We don't need to secure the whole planet and the plan depends on a bulky, cumbersome set of equipment.
Unobtainium? Great name...
This guy goes out there and doesn't do his job, rather aims to get laid. He also somehow manages to figure out a lot of the biology without any problem and catches a big ass bird he knows nothing about. Since we know he'll get the bird, why not show us the action involved? Going to black and having him showing up suddenly with the animal? Yeah, not very climactic.
The story is basic. The lights were many. Same argument I had with Star Trek.
I think monkeys could manage to some degree. Afghanistan did quite well against the Russians even before our intervention. BUT, when you step up the firepower to a certain point, the burning rubble of their treehouse is pretty much all that should have come of it.
Anything done on a technical level that has not been done in film before? Nope. Star Trek II: The Wrath of Khan, Beauty and the Beast, Final Fantasy or Star Wars: Episode I accomplished more on a technical level. Cameron didn't push to do new, just better at the old. That's fine and good, but even Willow did something never before seen and still got bashed as an overall film.
