The wild glory of the visuals will take your mind off the dopiness of the dialogue.

It is admirable as a viewing experience, but it has none of the emotional conviction that makes a true movie classic.

It would be missing the point to call the proceedings indulgent to the point of self-infatuation: Cameron has built a new world from the remixed bits of this one, and he seems determined that we should not simply visit Pandora, we should live in it.

Oona Chaplin as Varang is easily the best and most intriguing part of this film and the visuals of Pandora remain fantastic and vibrant.
