This is a great movie. I watched it 5 times. It has a great message, like how not taking care of the planet can result in human extinction. It has the s word a lot and some other milder stuff, but no f word. It does have smoking, and grace uses the b word a couple of times. But the role models are great! they are trying to save the Na'vi's home and world and they are on the good side. The captain general dude would probably scare little kids because he's tall, muscular, and has a HUGE gash-scar on the side of his face. There is a huge violence problem for younger peeps because it involves stabbing, shooting, dying, people getting shot down as they run away, the leader of the Na'vi's getting a huge ol' stick flung into him and he dies, explosions, gas bomb things, scary airships with lots of missiles, and big robot things the humans get into that have big guns and giant knives. Jake does have a big gun and tries to shoot a big beast. There are a lot of scary animals that kids mite be scared of and the general is in a robot suit an keeps repeatedly stabbing a scary beast over and over until it dies. Near the end jake is in his avatar thing machine and the window breaks and they start losing oxygen and jake tries to reach his ventilator oxygen mask on the wall, but because he lost his legs (not in the movie) he can't reach it and is clinging and goes unconscious. little kids think he dies. then netyri comes in and saves him by putting the oxygen thing on him. Greta story line, but a little scary for little kids.
