Along with "Schindler's List," this is a stark, brutal re-enactment of actual events in possibly the most brutal and horrendous of all the concentration camps, Mauthausen. The film faithfully chronicles a true story... perhaps too faithfully for the faint of heart to watch. This finely acted film, which must have been excruciating for the actors to work on, is a must-see for its historical value, not for casual amusement (there's nothing amusing about sadism, unless you're a Nazi). The recreation of scenes the real photographer captured is amazing for their detailed accuracy, and the film brilliantly brings the images, originally captured in black and white, to life. I rated this film an "8", which I deem a very high rating, only because production values were not of top-notch calibre... but, then, they really didn't need to be for this film. The setting, along with the acting, was perfectly believable as is, and you'll be sucked into a nightmare as soon as the film begins... and stay there until the last few minutes. That alone makes this film a huge success.
