I think that, ultimately, most viewers would rather have a movie that presents a picture of humans having a chance at triumph, rather than one where the truth of the story is that we cannot win (because the computer overlords are merely simulating our win to placate us). The latter is far, far more dystopian.

Interestingly, the Thirteenth Floor did a pretty good job of that overall premise (sims inside sims), but without the dystopian overtones.
