It have good cgi but story is as stale as a food can be.

Basically it's a very average family movie story.

Jake sully the main hero of the movie was not used at all. They could have made this movie without him.

No magic moments in movie, just a good cgi and VFX.

They wasted this part in introducing his children and specially Grace daughter that she could be a superhero in Avatar movie.

Representative attempt of losing kids and fighting to get them back was a loop.

Apart from new kids, all old characters are live now as a Avatar no that itself a bogus attempt to continue story.

It just doesn't make any sense.
