That's according to Debbie Schlussel, who reviews films regularly.
She says "Avatar" is "long, boring, unoriginal and uber-left." From the way she describes it, it is another eco-freek paean to goddess Mother Earth, with evil capitalists trying to destroy another planet, "Pandora," in order to reap the mineral benefits buried in its crust and kill off the peaceful, loving and attuned-to-nature Pandorians, who look like painted Indians.
The left wing tripe coming out of Hollyweird these days almost writes itself.
