Aliens is the magnum opus of all action films, one of the finest examples to show to your kids of what a great movie really is. There is no sex, no nudity of any kind. There's funny, well-written and extremely memorable characters. The foes are scary and must be destroyed, nothing morally wrong with kicking these aliens' butts. The film actually deals with this in an interesting way, the company wanting to spare the aliens - not because they care for them or anything, but because they want to study them (and most likely use them as weapons/or something else unnatural). Ripley is a great hero all the way through, aided by a group of marines who seem like jerks in the beginning, but really flesh out towards the end. The special effects were fantastic for it's day, and still hold up incredibly well - if this movie were made today, every alien would be a gray computer generated lump running around in 3D, which would destroy..honestly the entire film. The aliens are scary because they feel real - real props, models, puppets, and people in suits were used, which delivers a really visceral feeling to every encounter. The violence is not gratuitous, but instead very courageous and heroic. There are scary moments ... but ... really stop shielding your children from everything. This film is a classic. The younger generations need to see films like these so we get more great, inspired creative minds creating epic films and other forms of media such as this in the future. If you wait too long to show your kids this film, they'll look at it and pick it apart. You can't protect them from everything, so they would already be exposed in some way to (or at least hear of) more violent / scary things, most likely stupid things too. Like cheap run of the mill "found footage" nonsense, and they will get a misguided perception of the horror genre. This film educates, really. Aliens is a classic (and so is the first film, Alien) It's a great movie for younger people to see, as it might give incite to them as to what a great film is.
