Satoshi Kon's Paranoia Agent. Its relevance to rationality lies in its criticisms of various kinds of self-deception rather than positive accounts of methods of rationality. A variety of sub-themes orbit the core theme of self-deception: status-obsession, escapism, nostalgia for idealized imaginary past, hypocrisy, externalization of responsibility.

Note though that Paranoia Agent drives the message home not by didacticism and realistic portrayal of situations but by appeal to gut-level feelings and ample nightmare fueling.
