"What is Unobtainium anyway?"
Neatorama has some problems with ‘Avatar’ and proposes a theory as to how to explain some of its plot-holes.
“Unobtainium is a humorous name for any extremely rare, costly, or physically impossible material needed to fulfill a given design for a given application.”
That’s it: it means it’s an impossible-to-get-at substance. And no, for those of you that are asking that question, not once do they tell us what the heck it is or what it does. This leads to a host of questions about the motivations of the human beings and what the crap they’re doing there in the first place. One explanation that I shall now put forward, however, simplifies things greatly.
Unobtainium is a drug.
(I still have yet to see ‘Avatar’.)
