I just watched Avatar: The Way of Water. Like the first film, it's very pretty, but very full of stereotype and clichés. The noble savage and nasty military baddy are probably the worst examples, but there are several others.
The baddies are not quite so insanely nasty and utterly lacking in anything remotely resembling empathy, they're merely very nasty, and not quite as completely stupid. The story isn't a great deal different from the first film either, just done in water with swimming beasties instead of flying beasties and jungle.
I do wonder what they'll do with the other films, since they've exhausted the obvious variation of the environment. They've used water, jungle and the air. They could possibly do something in an arctic or dessert environment, or maybe there are vacuum evolved Na'vi? They may have to resort to actually trying to vary the storyline.
The characters are rather flat, and most of the acting is tolerable, although I presume a lot was achieved with motion capture and studio recording, given the extensive use of CGI. Even on a small screen the imagery was impressive, and I may try to watch it on something larger.
