I am convinced that Medicating Normal is the best documentary ever made about how psychiatric drugs destroy people. Everyone with an interest in psychiatry must see this brilliant and very moving film. More than once, actually. The film can be seen for free.
For over three years, the filmmakers documented the journey of five individuals whose lives were profoundly impacted by the medication they were taking and they interviewed many knowledgeable experts about the central issues.
The homepage for the film is very informative, with resources related to psychiatric drugs and how to withdraw safely from them.
