The series presents the story of the Stanford Experiment. It's divided into three episodes. The first presents the most well-known version of events, the second focuses on criticism of the methodology, the experiment, and the presenter himself. The third episode allows everyone to express themselves freely and present their own version, including Professor Zimbardo.
The series' appeal depends largely on how little you know about the Stanford Experiment. If you don't know much, the series can be a bit chaotic. For example, Professor Zimbardo isn't named until halfway through the first episode, so if you weren't familiar with him, you might wonder who he is. The series will be much better for intermediate learners. It includes many details that aren't widely known, so you can expand your knowledge if you already knew something before watching the film. The interviews with the participants and the experimenter are very informative.
The program allows them to express themselves completely freely, and what some of them say is truly shocking. It's not about what happened during the experiment, but how all these people came to terms with the experience. For example, one of the "prisoners" says he faked it to be released, one of the "guards" says he only pretended to be evil to subvert the system, and the experiment's creator has absolutely nothing to reproach himself for and considers any criticism groundless. All of this is somewhat reminiscent of a popular song in my country by soccer fans who, after losing a match, celebrate that nothing happened and will win in four years.
It's also worth noting the bitter reflection on the media and scientists (though this is more my observation than the film's message). Although the Stanford experiment was-to put it mildly-very controversial, and its official results-to put it mildly-not very reliable, no one questioned it for over 30 years, and Professor Zimbardo was an undisputed authority and public figure. Although today the Stanford experiment is heavily criticized and its results are less and less recognized, it did happen in 1970. The fact that so many years had to pass unfortunately does not reflect well on either the media or other researchers.
