Amazing yet challenging film. Unique, w/intensely detailed cinematography, costumes & sets & although it's an examination of humanity's inhumanity & suppression of science & intellectualism, it's worth screening if you can handle the many oddities, ambiguousness and repeated dark motifs/focuses, Many have posted it's undecipherable, and parts of the film are 1000 times harder to follow than even the most bizarre movie you've seen prior. It both follows the book but doesn't. Weirdness aside: Humanity discovers an Earth-like planet populated by human beings stuck in the middle ages & sends a scientist to study this world by residing amongst them as a one of the feudal lords. He wants to help lead them upward from ignorance, but is held back by non-interference policies. Will love prevail? Yes, it's weird, repeats themes of mud & stench & viscera et al, is often silly, breaks the fourth wall & so on, yet it's filmed so well as to transcend its oddness for at least one screening. The book made far more sense and the often made fun of German version seemed to follow the book more closely & both are more easily approachable than this truly amazing yet yet ultimately emotionally dreadful film because it imparts an intense feeling of humanity at our worst & of a modern man seemingly stuck & quite alone, in a perpetually dark, wet, muddy, chaotic and gruesome reflection of Earth back in the day. There are some moments of beauty, like when he plays jazz on his oboe-like instrument. But for the most part an intoxicatingly well-produced, well-shot period piece set in a sci-fi context barely touched upon that leaves a lasting impression both of its high level of mastery visually & of its reflection of us shall we say not at our best. If you read the book or at least skim it prior to viewing, it will make a lot more sense although like certain other films by, say, David Lynch, Hard to Be a God exists in a unique realm all its own. A masterpiece, but one that both triumphs & suffers from its often frustrating lack of key pieces of the novel which would aid most viewers mightily.
