Common Sense Note
Parents need to know this highly anticipated James Cameron sci-fi epic may be too intense (and long, at 161 minutes) for some tweens. There are several effects-heavy battle and hunting sequences that include missile-launching military aircraft, nerotoxin-laced arrows, scary Pandora-dwelling fauna and flora, and lots of explosions -- all of which has more impact when the movie is seen in 3-D. Salty wartime language includes many uses of "s--t" and comparable words. As in his previous epics, Cameron infuses the action-driven story with strong female characters and a morality tale centered in a romantic relationship -- though the human-Na'vi relationship in question gets a bit complicated, because the human is actually in his avatar. The romantic leads' chemistry is made more sensual by the barely dressed bodies of the Na'vi. (Note: Fans of the animated series Avatar: The Last Airbender should know that this movie is in no way connected to that show or the movie based on it.)
Sexual
Content
Many longing looks between Jake's avatar and Neytiri, which eventually leads to kissing and "mating" (only kissing and touching are seen on screen). The Na'vi's humanoid bodies are barely dressed.
Violence
Characters (supporting and extras) die due to explosions, bullet wounds, arrows (some treated with toxins), precipitous falls, and asphyxiation. There are several intense scenes involving frightening Pandoran creatures and plants, as well as tension between Jake's rogue group of pro-Na'vi humans and the rest of the humans sent to Pandora.
Language
The word "s--t" is said several times (as well as its brothers, "bull s--t" and "holy s--t"). Other colorful language includes "goddamn," "piss," limp-dicked," "hell," "oh my God," "ass," and mild insults like "stupid," "ignorant," etc.
Social
Behavior
Overall, the movie's message is that we could all stand to learn something from a (fictional) peaceful, nature-loving alien population. Strong environmental and pro-peace themes. Some viewers may see the message of occupying a foreign land to usurp their cultural riches as a political dig at America's involvement in the Middle East.
Consumerism
No product placement in the movie, but there are dozens of tie-in merchandising deals tied to the title -- including toys and books aimed at young kids.
Drugs / Tobacco /
Alcohol
Sigourney Weaver's character, Grace, smokes cigarettes and somewhat glamorizes the activity.
