James Cameron paints a very black and white picture of what's good and what's bad in Avatar, and pretty much continues the same into the second installment which automatically kills the possibility of having any intellectual conclusions about the movie. Cameron never really addresses the flaws in his world building and just proceeds with humans bad, Navi good, therefore humans lose and Navi win.
Considering how Navi are the most intelligent and apex predators of Pandora, they would have very few natural predators and with their seemingly advanced knowledge of medicine would most likely have a decent life expectancy. Plus they have a very human like tendency to stay in family units which further increases the chance of a Navi offspring reaching adulthood. With all these factors, Navi should have dominated much of Pandora's habitable land which I confess is appropriately shown in the movie. But what it doesn't show is rival clans competing for the same space. Territory is prime commodity not just for intelligent life like humans, but also for animals which needs to be fought for. But the Navi are too good to fight amongst themselves. What's stopping the forest Navi from waging war over the ocean Navi and vice versa given there is no trade amongst them and they're clearly aware of each other? Another thing is how selfish the Navi are when Sully's wife threatens to kill the Mowgli kid, ignoring the fact that he grew up with them and helped them along the way. All because he isn't one of them. Contrast this with Jake sully and the other humans who went against their own species just to save the primitive Navi. It clearly shows humans are the more compassionate amongst the two so why should I root for some selfish blue monkey clan to win? And I also love how there are no mutineers amongst the said blue monkey clan, probably because they have the same amount of brain cells Cameron expects his audience to have.
I'm aware that the main theme of the movie is about colonialism but it does a very poor job of convincing why it's bad. In the first movie, the humans agree to bring technological advancements and infrastructure to the primitive Navi in return for their land but the Navi are far too holy to be needing all of that. Fast forward to the next movie and they're using wireless communication to plot ambush attacks on a weapon supplies train. All this led by an ex human Jake sully. This eerily resembles another well known movie about colonialism, the movie being Lawrence of Arabia. Jake is clearly the Lawrence in this universe. Without Jake, the primitive and dumb Navi wouldn't have stood a chance against humans which clearly shows how superior the colonialists and their technology were. But unlike Lawrence, Jake doesn't have to deal with the aftermath of the revolt and fails to see the reality in his persuit of glory.
With the bulk of my gripe out of the way, there still remain some biological queries like are the Polynesian looking ocean Navi a different species from the Jungle Navi? Because they obviously have anatomical differences. Are they like Cro Magnons and Neanderthals? And do they have enough genetic similarities to produce an offspring? But again their highly adapted anatomical differences offer no advantage over the jungle Navi with a few days of swimming lessons. Only Cameron can answer these questions.
On the technical side, the cinematography and film score was pretty mediocre and relied too heavily on the visuals. I don't want this review to be as long and arduous as the movie itself so to conclude, I can't wait to see Avatar 3 Way of sand with brown Navi and the same old incompetent human mercenaries.
