Serial Experiments Lain, The Animatrix Recommendations
“Is this the real life? Is this just fantasy?”
Serial Experiments Lain and the Matrix franchise share the same themes:
What is reality? Can we trust in what our senses tell us? Is there another reality beyond that we can see?
The theme of both show is the uncertainty of what is real and what isn't, scifi that involves technology in some sort of huge conspiracy.
