Scariest film

If you haven't seen it, the 1978 remake of Invasion of the Body Snatchers is free to watch on Netflix for the next few days.  If you have, there's a nice article (with spoilers) here.

What makes the movie so scary is that it highlights the vulnerabilities of human society.  We're pretty tough to beat in a frontal attack.  Once engaged, humans are tenacious, ingenious, and remorseless enemies.  Other animals know to stay away from us.

But we're not so good at dealing with stealth.  And our high-trust societies are constantly vulnerable to betrayal.  And we have to sleep at night, a moment of supreme vulnerability.  And we reproduce slowly.  A stealthy enemy, capable of infiltration and unencumbered by the need to sleep - with a high reproductive rate - could exterminate us in pretty short order.

Oh well, time for bed...
