With over a decade of technology improvement, the movie provides even better visuals, more believable CGI(not that the first one didn't), it also continues the beautiful cinematography.
But, the script is far inferior to the last one. The movie tries to focus on "family", and with Jake and Neytiri already had a movie, this one focus heavily on the children. But most of the plot lines fall into the trap of being a set-up for sequels. A few plots left unanswer in the end and a few plots begin after the mid point and already wrap after just after being introduced. Some of the charcaters are downgraded into 1 dimensional and some do not learn anything meaningful throughout the story. And the focus of the movie shifts completely once entered the third act which diminishes all the set-up from before.
In conclusion, definitely a must watch, better visuals but slightly worst script.
