I was satisfied with merely telling Sean and Kegan that the plot of "Avatar" was just "Pocahontas In Space"...
...but Matt Bateman (warning: very non-Baptist language at the link) got a lot more empirical:
Since that's probably too small to read, I'll transcribe it:
16072154, a ship carrying J ohnake S mithully arrives in the lush "new world" of North AmericaPandora. The settlers are mining for goldunobtanium!, under supervision of Governor RatcliffeColonel Quaritch. John SmithJake Sully begins exploring the new territory, and encounters PocahontasNeytiri. Initially she is distrustful of him, but a message from Grandmother Willowthe Tree of Souls helps her overcome her trepidation. The two begin spending time together. PocahontasNeytiri helps JohnJake understand that all life is valuable, and how all nature is a connected circle of life. Furthermore she teaches him how to hunt, grow cropstame dragons, and of her culture. We find that her father is Chief PowhatanEytucan, and that she is set to be married to KocoumTsu'Tey, a great warrior, but a serious man, whom PocahontasNeytiri does not desire. Over time, JohnJake and PocahontasNeytiri find they have a love for each other. Back at the settlement, the men, who believe the natives are savages, plan to attack the natives for their goldunobtainium. KocoumTsu'tey tries to kill JohnJake out of jealousy, but he is later killed by the settlers. As the settlers prepare to attack, JohnJake is blaned by the IndiansNa'vi, and is sentenced to death. Just before they kill him, the settlers arrive. Chief PowhatanEytucan is nearlykilled, and JohnJake sustains injuries from Governor RatcliffeColonel Quaritch, who is then brought to justiceshot with arrows! yo. PocahontasNeytiri risks her life to save JohnJake. JohnJake and PocahontasNeytiri finally have each other, and the two cultures resolve their differences. IMHO - Matt Bateman
I'll probably do a review of Avatar, but I'll have to do it over at the politics blog, because the fact is that Cameron took a wonderfully, astonishingly, richly imagined and incarnated world...and, being in a position to tell absolutely any story he could possibly tell in that world, from any genre, with any point, the thing he was most eager to do...was to create a pathetic far-Left revenge-fantasy in which he could with the greatest of glee kill off, on-screen, as many American Marines (carefully and explicitly and repeatedly identified as such) as his little heart desired. It's a nakedly, shamelessly, and bordering-on-mentally-ill hate-driven political piece. What a tragic waste of a genuinely breathtaking and exhilerating product of a towering and powerful imagination.
But to discuss it in detail requires the sort of post that I have banished to the political blog.
