* No one in the Sully family gives a **** about Spider until he shows up again. No one cares that he's being held captive.
* Neytiri threatens to kill Spider, and no one calls her out on that. Neytiri was in a vulnerable situation at that point yes, and she was dealing with a lot, but like...how is Spider supposed to feel about all of that?
* I don't think the movie properly built up Neytiri and Spider's relationship and that she doesn't view Spider as one of the family. She clearly has no paternal instincts for him to threaten him in that way.
* The 48FPS looks too inconsistent. The technology is a gimmick and doesn't look good. It makes certain scenes look choppy and bad. Other scenes look too smooth and artificial.
* General Ardmore disappears midway through the movie.
* Also once they leave to go to the reef, they kind of ignore the fact that they are in a winner takes all war. Not sure why they think they can just disappear to the island region and never worry about the RDA again. The RDA is there to stay. They literally want to colonize all of Pandora. What about the sanctuary area? That's what they were targeting after destroying home tree in the first movie.
* I get that they have multiple movies, but to spend three hours for Jake just to realize "Hey, we have to fight for our home," felt kind of redundant. Like the first five minutes of the movie we see the RDA returning to Pandora and causing massive destruction. I get that Jake just wants to protect his family, but schlepping off to the island regions is not a solution for that. Jake is an idiot.
* Literally no mentions of unobtainium ever again, lol. I guess they solved the unobtainium problem on Earth. It's all about the Amrita brain juice now.
* Once again, I get the wider implications are probably being saved from other movies, but I mean...the obvious answer here is that Earth and humanity are screwed. In order for Pandora and the Na'vi to survive, it basically means they have to wipe out humanity. And what I mean by that is it doesn't look like we are at a point where peace can be brokered and humanity can live in harmony with the Na'vi and Pandora.
* Unless we get to a point where the combined forces of Pandora can figure out a way to beat humanity into submission before killing them all that they would have to submit to all their laws and rules.
* In other words there's no simple, peaceful resolution here. It's a pretty dire situation. Humanity has condemned its planet to a grimy death. They can't be allowed to do the same thing to Pandora.
