I finally got to see it last night!
It was good.
Outstanding FX. Almost certainly the most gorgeous movie I'd ever seen. Although afterwords my wife and I kept talking about how similar the plot was to
Dances with Wolves. It's almost exactly the same! But that's not a criticism: "noble savage" scripts tend to do very well (
Dances with Wolves, Braveheart, The Last Samurai, etc. Nothing wrong with that, it's just a re-telling of an old story. The entire
Star Wars genre is a re-telling of an old archetype story, so I won't complain about Avatar's plot.
I have some criticisms, though. Off the top of my head, the casting of Giovanni Ribisi as the civilian in charge of the corporate mining operations on Pandora was a piss-poor call. He'd be a great lackey working for the character, who should've been a good twenty years older. The Colonel character was played better than I expected, but still came off as a far-fetched charicature of an actual soldier. And quite a bit of the scenery (the floating mountains in particular) was so outlandish I can only assume it was put in there because it looked amazing. Just what the hell causes mountains to float? Pilots briefly referred to a "flux" area, but that couldn't stop me from shaking my head at the sight of it. Na'vi have to climb up the damn things: if the rocks float in the area, why doesn't anything else? Maybe there's a rational explanation, but they didn't spend the ten seconds worth of screen time needed to explain it. I don't think the sight of the "unobtainium" suspended over a gadget on Ribisi's desk covered the concept of how those mountains came to be. Things like that shift the focus of the movie from the high-budget morality tale it was meant to be to one which seems to be an opportunity to display a fantasy with a plot plugged into it, since movies do require a plot.
Overall, 4 out of 5. And maybe I'll get it on DVD.
