10 Sci-Fi Movies That Get Better The Deeper You Go

7. Wall-E

On the surface, Wall-E is a touching Pixar story about the last resident of Earth (other than the cockroaches, inevitably) after the man-made trash apocalypse, doubling as a gentle, delightful meditation on love and loneliness. It's the story of a machine learning human emotions from exposure to old romantic films and then unwittingly inspiring the resurrection of the human race from enforced stasis and the repopulation of Earth. You know, the kind of thing ALL kids like.

But Wall-E is even more rewarding when you start to wonder about how the Earth got into the state it got into, because you begin to see hints that the company that seemingly "saved" humanity with its off-planet ships might actually have been behind the planet's fall into inhospitability.

And that's not the only sinister theory out there - there's another that suggests Wall-E is actually Satan - or the only reading that changes how you experience the movie or appreciate its depth. Wall-E is way more about the human condition than it is about the little robot that could and awareness of those implications just makes the central story all the more rewarding.
