I watched Harvest and I thought it was fantastic. What a creative approach. I am a big fan of Psycho Key and actually flew to Geneva to see their multimedia production. I understand that Jolliet's initial purpose of making a musical film was to have his band Psycho Key interact with it on stage. That idea alone was very impressive.
But when I saw the completed film, I was blown away by his success in intertwining the storytelling with the music. The songs continue to carry the story through their lyrics. What a brilliant, unique concept. I applaud Jolliet's work, as I was taken on a wild ride watching Harvest, and there was no need for any substances to take me to that 'trippy state'.
The intent of Harvest is obviously not 'plot-heavy', and I don't think the goal was for the audience to deeply relate to the characters, but simply to enjoy watching them. What stands out the most in the film is entertainment of the band. Their music is very powerful and hypnotic. But there are definitely some very intense, well-written dialogue scenes.
Harvest was Jolliet's first film, and again, I commend him on his work. He has proved himself as a talented filmmaker, and I hope he will continue on that path.
