There is a big horrible polluting machine that can possibly be used to harvest the $$$$ making stuff from the planet. Humans are mostly villains. They do not consider the consequences of what they're doing. There is a culture of people who live in the area that humans want to destroy. Humans do not care. Etc etc.
I didn't watch most of this movie because A: I was bored. And B: It looks fake to me.
But I saw enough. Enough to know it was totally ripped off from another underrated classic movie. Yes. I'm talking about Ferngully, The Last Rainforest.
Ferngully is about evil humans who want to chop down the "last" rainforest to make some $$$$. They use a big evil machine to cut down the trees. This rainforest in inhabited by tiny little fairies, who fly around talking about how trees feel pain and such. Then a human accidentally gets turned into fairy size and makes a love connection with a hot fairy. Sound familiar? (Just substitute hot fairy for hot blue Na'vi Zoe Saldana).
Eventually the human sees the error of his ways and helps the fairies battle the evil giant machine to save their mother tree.
There are to many parallel story lines for me to even remember. Evil greedy humans. Check. Interspecies love connection. Check. Trees that feel pain. Check. Liberal agenda. Check. Happily ever after(ish). Check.
It took James Cameron years to finally complete Avatar. I think he was probably just waiting for everyone to forget about Ferngully.
If you ask me, Avatar could've used a little more singing and dancing. And maybe a bat voiced by Robin Williams.
