Below any substance except visuals. That pretty much sums it up.

Part one was a visual and computer animation revelation with a story to be pretty much expected, nothing special, but good enough, fitting and supported by the visuals. Part two is visuals only and not even impressive ones, cause you are getting used to them, especially from Cameron. And that's the problem these days: this is simply not enough. You need a movie too, and Avatar 2 is none. It's a compilation of effects and Camerons technological capabilities acquired over many years. The story is ridiculous, the characters are, the lines are lame, the Pandora magic is gone, the new "Pandora gold" the sky people are harvesting is a joke only brought in to bring the story in the water from the sky people side, but boy, so badly done.

With this movie and all follow-ons Cameron doesn't do himself a favour, as he didn't do before with his Terminator reincarnation, which was a total failure. His days are over and he shares this fate with his director buddy Ridley Scott, both never should have done any more Alien or Avatar movies. But it happened and the result is abysmal.
