what does that mean?
"Unobtainium" is an old joke among engineers and science fiction writers. When the science fiction writer says he wrote a story about an airliner that will go 5 times the speed of sound, the engineer replies "That would be nice, but if you're going that fast, the thing will heat up to thousands of degrees and melt the skin! What are you going to make it out of?"
The sci fi writer says "Unobtanium". Basically, it's a way to hand-wave away all of the technical problems by saying "we'll find some magical new material that will do what we need it to do. Meanwhile, let's get on with the story!" See also adamantium
As for the movie, I thought it was great. It's a technical masterpiece. If you want to see it, you've got to see it in 3D. Cameron uses the medium very subtly, and does things I've never seen before. It may prove to be The Jazz Singer
. And if you're going to bitch about his writing, start with the inherent grandfather paradox
