This - for me, at least - contains some of most gripping moments in film and tv history. These moments, in which test subjects are debating whether or not to obey orders against their better judgement, are highly charged with human drama, and even though we know that what's really being tested is whether they will stand up to an authority figure who is asking them to do something evil, they do not, so the stakes are through the roof. I would implore anyone to watch it (if you can track it down).
