I read this article while waiting for the movie to start http://edition.cnn.com/2010/SHOWBIZ/Movies/01/11/avatar.movie.blues/
And my friend and I were laughing about it. what the heck, how could 1000's of people be suffering from depression about this fictional world. it didn't make sense.
It's strange because while the movie was on, i was not on Earth, I was on Pandora. I was so emotionally invested in the movie, that i felt like i had visited this amazing fictional place. Even if you would have asked me after the movie, i would have told you yeah, Pandora is a real place. It absolutely is.
The Worst part of the movie experience was walking outside of the movie theatre. You're definitely back on Earth, and it sucks ( in comparison to Pandora). I spent the night thinking about the movie... and the next day, and the next day. All happy thoughts on how amazingly the movie was made. And wondering if there really is a planet out there that parallel's Pandora.
I don't think that Avatar causes depression. But i do think if any movie is going to magnify it, its this one.
