After reading many reviews and talking to many other parents, I finally took my kids to see Avatar in 3D. They are boys aged 10 and 6. I did not think the violence was a concern at all. There was no blood and all of the action is seen from a distance. There were fire balls and explosives, but no close-ups of anyone dying. I also did not think the sensuality ended up being a concern. There is a brief kissing scene, and the term "mating" is then used as a synonym for marriage. There is never an overt reference to sex. The na'vi people wear very little clothing, and there are a few scenes shot from a distance where you can see the side of a female breast with nipple. Since it is from a distance and from the side it is mostly in shadow. Throughout the rest of the movie the breasts are mostly covered with ornate necklaces. I also was not concerned with this matter since these are a native people and not portrayed to be human or expected to be dressed as such. I did discuss this matter with my kids beforehand. The language is extremely rough and not used just in the battle scenes. The movie starts with adult language and the language is used throughout. Though I knew there was adult language in this film there was a lot more and more continuous use of adult language than I realized. This proved to be my largest concern, though I discussed this issue both before and after the film with my children. I think most of the language was gratuitous and did not add to the intensity of the film. Whether or not you take your child will need to hinge on whether or not you believe your child can hear these words and still have the maturity to know not to use these words. There are numerous uses of a**, sh**, g**-da**, and some terms that a curious child might want to have explained, such as limp-d*****.
