Alright. Sorry it's taken me so long to post this. Thursday (the day before I saw the movie), 45 minutes before my last class of the semester, my computer, WITH MY FINAL ON IT (and no other copies), decided to just stop working. So I've been without a computer (it's being fixed for free by Apple at the moment - and yes, they were able to get my final off the hard drive in time for me to not fail the class) since Thursday. I'm using my brother's right now (just got back to Indiana from school today).
Anyway, I saw it in IMAX 3D at Navy Pier on Friday, and it absolutely blew me away. It's the first movie that's ever truly convinced me that we can now do ANYTHING we want with CG effects, and do it convincingly ... and that, honestly, scares the shit out of me.
It's also the first non-documentary 3D movie I've seen where I felt the 3D actually added to the experience rather than detracting from it. I have a suspicion that the CG convinced me so much because of the 3D, but I won't be sure of that until I see it in 2D.
Now, many here have been saying that the story is bad. It's not bad, it's just very derivative. It feels like Dune and Dances with Wolves mixed with whatever the hell James Cameron was smoking when he wrote it. And I don't really have a problem with that - the first Terminator was a huge ripoff of (I believe) a Twilight Zone or Outer Limits episode, and it's one of my favorite movies.
The action is very well staged, even if I had a bit of trouble figuring out just what the hell was going on in the big, epic aerial battle at the end. I forgive that for the sheer awesomeness of the film.
Sam Worthington managed to put a very relatable face on what must have been, on paper, a very unrelatable character. I can feel his disillusionment with the "real" world grow throughout the film. Zoe Saldana (though we never see her as a human) did a very good job as well, though I'm not sure how much of her performance was CG-enhanced after the fact.
I have two minor problems with the film. The first is the dialogue. I know dialogue has never been Cameron's strong point, but almost every word that comes out of that scarred mercenary's or Michelle Rodriguez's mouth sounds ridiculous.
The second is very nitpicky, but it distracted me. The subtitles don't blend well with the 3D. It's fine and undistracting most of the time, but once or twice there was something that clearly should have passed in front of the subtitles, but didn't. It threw the depth perception of the shot off completely every time it happened.
In short, I absolutely loved it. Seeing Avatar in IMAX 3D felt like what I'd imagine seeing Star Wars for the first time in 70mm would have felt like. I recommend it to everyone, even VINH (though I doubt he'll see it).
