Continuous jumps from documentary to fiction, the sad thing is that the recreated scenes seem artificials and, unexpectedly, less disturbing than actual archival footage. I would rather listen all the four hours that delicious russian oldie. Anyway I stopped halfway.
I watched this entire film in one afternoon. I then slept peacefully. This means I was either engulfed in a traumatic fixation of the rubbernecking variety, or that I am an irredeemable sociopath. I like to think it's the former, but it may be a bit of the latter. Recommended if you want to feel an unending, often unwanted connection to the historical events of Unit 731.
