I think it's a great film (even better viewed whilst eating a Ben & Jerry's hot fudge sundae). The concept of only taking what you need from the earth and giving back is a very relevant one. The 'war on terror' that the humans wage on the Na'vi in order to mine the Unobtainium (hi, worst name ever) is also very topical.
However, there have been communities set up by people that think they used to be Na'vi. People who actually believe they've been hunters and ridden Ikran. People who claim to have memories of their time on Pandora.
I have but one word for that...
No.
But, if it does turn out to be true then let my introduce myself. I'm a Fourth Generation My Little Pony. My name is Twiglet, I have a brown and white speckled body and long brown hair. I like crisps, marmite and jumping in puddles.
Neigh.
