One of the main problems with The Matrix Revolutions is that it's basically one long and rather tiring battle sequence, which transpires predominantly in the last bastion of human civilization: the subterranean Zion. Not everything about the scene is a total waste however. Despite being rather derivative, the mech warriors that the human defenders use to repel the machines' invasion are pretty neat. Additionally, the scene contains a pretty vicious level of brutality, which is practically unheard of now with big budget films. The mood that the Wachowskis create in this scene is also notable. Essentially, the human defenses are rather futile; they are a last-ditch effort, a Hail Mary. Still, the resolution that the directors came up with for the conflict is bewildering and in no way satisfying. What finally puts an end (at least temporarily) to the acrimonious conflict between man and machine is Keanu Reeves' Neo, who successfully negotiates a treaty with a being literally referred to as the Deus Ex Machina, also known as the central interface of the Machine City. While this spares the human race in Zion and gives them a "victory" which could never have been achieved through force, it hurts the film overall. It prompts a highly inconclusive ending, and leaves questions like: "What will the machines do for power now that they are freeing those people still plugged into the Matrix?" and "What exactly happened to Neo?"
