The movie is BEAUTIFUL, and if you're looking for an action movie I definitely recommend it. However, if you're an actual fan of Avatar 1, you will be disappointed.


Overused plot twists : [spoiler] bad guys that come back to life (terminator like), a boy raised by the Na'vi that is actually the son of the bad guy (jungle book / star wars like) [/spoiler]


Remakes of scenes from the first movie : [spoiler] Jake riding sea horses for the first time and falling, his son becoming friend with the most dangerous animal, Colonel getting his own flying pet... [/spoiler]


The apparition of useless characters : [spoiler] Spider (he hated his dad and then he decided to save him?) , the Earthers who stayed from the 1 (they just appear 10 seconds to help Jake's daughter), the female colonel who brings nothing to the plot, Neytiri's mother who appears for 5 seconds maybe... [/spoiler]

The lack of character development : they pretty much have 1 personality trait at the start and don't really grow from there, which is very different from the first movie - [spoiler] the colonel still hates the Na'Vis even after learning their language and getting his Banshee, Neytiri hates Spider from the beginning, the relationship between Jake and his sons... [/spoiler]

Lastly, and this is what frustrates me the most : the many stories started that do not have an end - [spoiler] how did the Earthers have time to go back to Earth and come back to Pandora in 10 years? Why is Kiri able to control Eywa? How is humanity planning to move to Pandora?...[/spoiler]

Overall, I would recommend the movie if you decently liked the 1st one and want to stay in the same universe. But if you are looking for an actual sequel with a great plot and story / character development, be prepared to be disappointed.
