It seems fashionable here to dump on this franchise.
People scream, shout, and stamp their feet every time these movies get brought up, yet it's the second highest grossing movie of the year, which is not bad for a 3hr sequel to a movie that came out 13 years ago. They were ready to hate it before they even saw the first trailer, and now they can't fathom that it's been a success. Every time I try to schedule a showing, the theater seating is packed! Which means the cash is still pouring in! That doesn't happen for movies with bad word of mouth. People are seeing this movie, and they are liking it and telling their friends to see it.
All I know is that I saw the movie last weekend and loved it. It's not 3 hours of straight action like a Transformer movie is, but it's far from boring. The movie is pure visual gold, and much more character driven than the first. In the first Avatar, Cameron made you fall in love with Pandora. In this one, you fall in love with its people. I'm going to see it again this weekend to see what I missed when I got up to pee. Also, I heard there was an after-credits scene I missed.
I don't think Cameron is bad, I just don't think he has any originality in him anymore. His old stuff wasn't just eye-candy, it was groundbreaking storytelling and directing. Now, it's just... blah. It's made for people who want to turn off their brains for 2-3 hours.
That's not me.
By Cameron's own words, The Terminator was heavily inspired by Carpenter's Halloween, but with robots.
Aliens and First Blood Part II are effectively the same plot but with aliens kicking US Marine butt instead of the Viet Cong.
Terminator 2 was just a repeat of the first movie with Arnold taking Biehn's role and higher production values.
Titanic was Romeo & Juliet laid over a historical setting.
And for all the comparisons to Fern Gully and Dances With Wolves, I found that the Avatar movies have more thematic and narrative similarities to Ray Bradbury's The Martian Chronicles.
As an aside, I do hope somebody ends up making a metal replica of the RDA-issued Avatar knives. I like the look.
