The titles comes from the literal translation for the Greek word 'Autopsy". And that's exactly what this film is . 32 minutes of intense, hand-held photographing of several autopsies in extremely explicit detail.
While the film is, by nature, shocking, and sometimes hard to watch, it's far from exploitational or sensationalistic. It invites us to meditate on life, death, the body, what miracles we all are, how fragile we all are, how alone we all are in the end, and yet how alike we all are. What is a human? What were these people like in life? Are all we are really just the blobby masses of brain we see being removed, leaving only empty skull cavities? Why is the film stomach turning? Why is it so hard to look at what is inside us all? Brakhage raises all these questions, and they are valuable and unsettling to consider.
That said, for me, the film could have been shorter. It started to feel repetitive, which I'm sure was part of the intent (watching ourselves become inured to images that only minutes earlier seemed deeply disturbing), but there was a point near the end where I started to feel I had gotten what I was going to already, including that last idea.
