Post Avatar Depression (aka PAD) is the condition whereby a movie-goer leaves the 'land' of Pandora in the cinema and returns to the outside world with depressive, unhappy thoughts and views. Due the the effectiveness of James Cameron's Pandora looking substantially nicer then our Earth, this concept is multiplied by the movie-goer. i.e. the movie-goer views the world as slightly pathetic, dull, boring, corrupt and unhealthy one. This can continue for days until the move-goer comes to term with the non-existence of Pandora (as of yet). Note that this condition can also be applied to the time after listening to 'James Cameron's Avatar' official Avatar soundtrack, as it produces many of the emotions (and the resulting reactions) movie-goers experience when leaving the cinema.
