The spoilers I am writing about come from a book called Mid-Flinx (written in the 90's by Alan Dean Foster) but so like Avatar I thought it may have been a movie inspired by the book. As I was sitting through Avatar, I found myself recognizing a lot of the concepts from something I had read before. Had to do some digging but found my old paperback and sure enough a lot of the stuff in Avatar could have been lifted directly from Mid-Flinx. Take away the human controlled Avatar and the rest of the story is insanely like Mid-Flinx a few different creatures but eerily the same. A human lands on a planet where everything in the forest is trying to kill him, found by a green colored alien female who starts to watch over him, teaches him how to survive in this planets jungle without being "disrespectful" to the ecosystem, when animals/natives die returning them to the earth as part of an cycle, being brought before the natives and eventually being accepted by them, the natives having (in Mid-Flinx) an empathic link to a single creature they bond with for life, a large tree where the natives live described in the book exactly like the tree in Avatar, a planet wide mind that exists in everything and links everything, aliens that come to hunt and are destroyed by the planet mind controlling things in the forest and the natives. Even the scene where they jump from the tree and use the large leaves to break their falls has a similarity to a part of the book where they jump off a branch and use a huge leaf to break their fall. I was bothered by these similarities. 1 or 2 similarities I can deal with but this was a bit much for me. Read the book and tell me what you think.
