Ha, here I am almost defending Avatar. I would rather watch Cops and Robbersons or Corina, Corina over Avatar.
Some good points, Chris...however, you are forgetting that we are getting old. Kids now don't have the attachment to the Millennium Falcon that they do with half naked blue chicks. It stinks, but is true. When the kids into Avatar now have their kids, they will show them Avatar and point to it as THE film...its a strong possibility, anyway (unfortunately).
The film does represent many important landmarks in its industry's history in terms of the technology involved, much like Star Wars in the past.
It handled the 3D thing in the biggest way. Remember, this isn't Journey to the Center of the Earth 3D with Brenden Frasier.
I could go either way on mine, personally. Right now, I am going to let it rot in the flat file, who cares. It's not going to nose dive to a $25 value anytime soon.
