Huge achievement to be able to gracefully showcase the inspiration drawn from the Indigenous Maori people of New Zealand for the Na'vi Water Tribe (Metkayina Clan)
The graphics were as expected, grand. However, the cinemas do not do justice. This a film you should also watch again when it comes out on DVD/Streaming platforms with a high definition TV.
It depicts anti-colonel and you see a lot of tragedy which is ultimately the same story many indigenous people have faced historically.
Overall, the film is exactly what you would expect. Though there is room for improvement from James Cameron's Avatar series.
