Matt Walsh's documentary asks What Is a Woman? Unfortunately, his documentary is every bit as much of a science denying propaganda film disguised as a documentary as antivax films like VAXXED or the anti-evolution film Expelled!, and such films tend to be potent messaging tools.
Under Our Skin is a propaganda film attempting to sell viewers dangerous treatments for 'chronic Lyme disease', a rejected diagnosis not recognized by any legitimate medical organization.
Afflicted is a documentary following the lives and treatments of people "diagnosed" with illnesses not recognized by science. Conversely, it could also be seen as a documentary illustrating the risks and harms of alternative medicine.
