Matrix & Animatrix

Animatrix are some short films that have a relation with the Matrix movies, they use the same places, the same machines and a lot of the things we get to see in the block buster movies.

In the especific case of the "final flight of the osiris", this short complements the movie because we get to know how Zion was warned about the machines that were destroying everything they could to get to the already mentioned Zion.
We get to know the characters that gave their life to save Zion and how they discovered what was happening and how they warned all of the others.

Some other details are that this short is one of the best because it is one of few 3D ( most of the others are 2D) and therefore it has better graphics and the other detail and maybe a personal one is that the music made by Juno Reactor which is great scoring.
