Homunculus is more of a curiosity than a good film but if you want to see what over 100 years old science fiction movie looks like you can check it. This should be well into public domain by now. You can get automatically translated English subtitles if you want. I think they were good enough to follow. I assume the movie is really weird by modern standards and it wasn’t because of automated translation. Translation from Spanish to English should be easier than from Japanese to English.
Story looks bit like Frankenstein story at first. This is movie about scientifically created man and his life. After first two parts it is less Frankenstein story. First three stories make some sense. Fourth and last don’t Things just happen in them without motivations. To be honest jumps between stories don’t make much sense either. First three stories have some internal logic but not much between them.
Not a masterpiece but interesting movie for science fiction fans. This is real silent film. There is no sound. What you listen same time will affect your experience.
