Still, I found the film to be very watchable and I was amazed -- and after thirty+ years in the entertainment industry I don't amaze easily -- at the totally new world and the attention to details in that world that he created. For me 'watchability' is a big part of something being classic -- i.e., it holds up over time. Think THE CARPETBAGGERS, A STREETCAR NAMED DESIRE, ON THE WATERFRONT. Soooooo many people found AVATAR watchable and I believe that's a good predictor of the film's future.
I think AVATAR will be a classic. I think people will still be watching it twenty or fifty years from now and enjoying it greatly. So I'll respectfully ask for it being, at this point in time, half-a-classic.
