You went to see Avatar for nuanced story telling? LolIt's undoubtedly a visual feast. The story is part multiple retreads, part new interesting dynamics but characters and story are still largely one Dimensional "goodies vs baddies". For those of us who love nuanced storytelling like in GoT where characters are flawed and complex, the Way of Water comes across as the most beautiful, visually flawless but most expensive kids cinematic cartoon ever devised.
Even the first one was like that and therein lies the appeal of these movies. Cameron is a smart man. Nuanced story telling? you may want to go somewhere else for that
