The tagline for this film is true. 9 is a very good film, and it features breathless, intense action from start to finish, but with moments of humor and quiet as well. In a post-apocalyptic world, the only shreds of humanity left are nine ragdoll-like creatures, whose names are numbers (in the order that they were created). 1 is the ruthless elderly leader, 2 is the inventor, 3 and 4 are mute librarians, 5 is the doctor/mechanic, 6 is the crazy artist, 7 is the fearless warrior, 8 is a Frankenstein-type creature, and 9, the final one, is our protagonist. They all try to save themselves from a mechanical beast that 9 accidentally activates. I do not wish to spoil anything else. In terms of content, this is borderline PG and PG-13. Despite the fact that there's no blood or sex, the dark atmosphere and threat throughout this film will no doubt scare some kids. Some of the ragdoll creatures have their life sucked out of them by a giant robot. Also, there are a few images of dead bodies, a severed hand (no blood, though), and war imagery. Other than that, there isn't any other offensive content. Overall, see this film if you're over 11. I also recommend the short film 9 is based on, but note that it's silent and somewhat more bleak.
