We first saw this movie on an airplane, Alaska airlines, with their portable movie box. It is really hard to hear and see a movie on an airplane, I don't care what kind of noise canceling earphones you have. So we ordered it from Amazon.
The movie is a bit hard to follow. But the short answer is that they are clones, their purpose in life is to supply body parts the their patrons.
There is a ton of action, it you were looking for something similar it might be Hunger Games.
Is it family friendly? I did not see any nudity other than one scene where there are some pinup girls on the wall. Obviously getting raised to be a body part is an adult theme. There is violence, but it is the kind of movie where they shoot a billion shots and no one ends up dead. There is also some hand to hand, but again it just is not realistic.
Will I watch it again? I am going to keep it on the shelf. It is fairly amusing.
