I've seen it, that is to say I saw it. I hope you guys don't mind if I get a little bit critical. Ok it looked amazing, particularly the flora, the alien plants and the world did look amazing, the fauna, the animals look pretty good too. I liked the black panther/dog things, I liked the hammerhead rhinos too. But I didn't think it was that good a story, I don't even think the 3D added anything to the film.
It looked great, but the 3D sometimes got in the way of the fast paced action. The story was predictable, but at some points very tense. I liked it when Jake was eating as his avatar was about to be squished by the giant JCB things.
I laughed out loud when I saw the general holding a cup of tea (coffee) as they go into battle. But so many problems.
Unobtanium was almost irrelevant, why blow up the tree when there were floating mountains, why were they floating? it didn't really say, they would expect us to assume that they were mountains of unobtanium, but then why not drag a mountain back to thier base instead of blowing up a massive tree that was 'sitting on the largest pile of unobtanium for 20 clicks'
Isn't a click about a mile or a kilometre? so are they that lazy that they can only be bothered to forage for this immensely expensive (imaginary) element within a radius of 20 kilometres on a forest moon light years from earth.
Where was this moon, it took 6 years to get there but they didn't say how, or where it was.
how come the general was able to breathe the air for more than 20 seconds, unlike everyone else he could just stroll out in it and start shooting (with his breath held?)
what was going on with the hair thing, how can a plait (I think thats the spelling) somehow include the optic fibre things that can act like brain wiring neurons? They just plait the hair together and magically the end has some things that talk to all the creatures, and then Jake even shaves some of his head, so how does that not effect the plait things?
I see James Cameron has upgraded his robot suit things from Aliens, cool.
the end battle was good when you got to see how big the Na'vi were compared to humans, the giant arrows were cool. Although at one point they couldn't pierce glass and they later on they could.
sorry for my rant, but I only liked the look of the flora and very little else about this film.

Shame
