It had good CGI and was a cool experience in 3D.
Other than that, it was trope upon trope upon trope stacked sky high. It basically felt like fanfiction of the first movie, complete with extremely predictable and cliché characters and plot, and a sensation of the world somehow being smaller or less thought out than in the original "real" movie. There is the romantic couple from the first movie now getting children, there is the adopted special Girl Who Isn't Like The Other Girls, there is the almost-adopted I Desperately Need Fatherly Love boy, there is the responsible personality-less oldest brother and the angst ridden rebellious second son. There is the other chieftain's rivals-turning-into-besties children, complete with Being A Love Interest Is My Personality TM. Oh and the I'm Just Small And Cute aka "Oh No I'm Tied Up Again?" which is an actual quote from her lmfao. And so many more characters. And the uh plot. Dang, mining in the forest apparently doesn't work anymore so let's find money in the sea instead, also You Killed My Body, Prepare To Die.
and.. honestly?
I think I expected something more like the first movie, to be wowed and feel like everything was truly alien. But if one enters the cinema instead expecting a heartfelt wholesome (and sometimes tearfelt) human story of family drama, siblinghood, friendship, fanfiction-like hurdles and such stuff you would expect in a "What happened to our heroes afterwards?" tale, then the 'plot' will be a cool bonus, the air and sea animations will be a beautiful bonus, and you might come to love the characters to bits. I know I love all the Sully kids, tropes be damned. They do their roles well. I've never liked Neytiri lmao, and Jake is just Jake. But Neytam was nice, Kiri is fantastic, Lo'ak is interesting, Spider needs all the hugs and uh the small one... yeah uh she's, just, there for some reason idk.
I'm not sure how many seashells out of five i'd give it, I feel like I want to re-watch the "real" movie first and see if I've just been having rose tinted glasses on (because I really liked the first movie). But Avatar: The Way Of Water wasn't terrible. It just wasn't mind-blowing or very smart either, and not what I expected.
I... I want to know what happens to them next. I hope they take care of each other. :)
