I was very surprised to see actual nudity in such an old, classic movie. But the movie itself was fine. The storyline about Perseus is mixed up somewhat (for example; Pegasus is created from the blood of Medusa, in the movie Perseus finds Pegasus to help him find Medusa).
the film wasnt that bad. If your not really a movie fanatic then you wouldnt mind to much about the poor quality, but if your the kind of person that gets a thrill from spotting mistakes in films... you would probably drive yourself crazy from the critical comments pouring out like water out of a tap.
