I really gotta see/hear more about the plot to get truly excited. Sure it looks great, but so does the first one on a big 4k screen. Love the visuals of Avatar. I tend to be a story person first so I am curious about the story of it. Have to be honest. For this one, I will likely read the detailed story synopsis when it comes out to help decide whether to see it in the theater.
Based on what I've been able to piece together from the trailers (going frame by frame), the story is the following:
The humans return to Pandora first year after the events of the first film, presumably killing a bunch of Na'vi and threatening Jake and Neytiri's home. Jake and Neytiri flee with their children and take refuge with a water-based tribe of Na'vi not seen in the original film and form a plan to try to stop the humans.
Subplots include:
Kiri — Jake and Neytiri's adopted daughter, played by Sigourney Weaver — having an unusual supernatural connection to Eywa, the Na'vi's goddess. Throughout the film she will likely learn how to harness her special abilities.
Lo'ak — one of Jake and Neytiri's biological teenage sons — develops a romantic connection with one of the member's of the water tribe of Na'Vi.
Spider — a human child adopted by Jake and Neytiri — being torn between the humans and his adopted family. Apparently, Neytiri isn't super accepting of Spider due to humans being responsible for her father's death. Spider could potentially make a villainous turn and betray the Na'vi. We shall see.
Colonel Miles Quaritch — the villain from the first movie — somehow comes back to life by entering an Avatar body. He will now struggle with becoming the very thing he hates.
While the general plot seems straightforward, I like that the sequel is introducing more interesting character dynamics to spice things up and prevent the film from being like a rehash of the first one.
