Should be used as an example....
.....on how NOT to make a film. But if you want a lesson in how to make a half-baked vanity project, than this is it. It shows the importance of screenwriting and having a complete vision for your project.
The best scripts are written with the ENDING already in mind. The scriptwriter's job is to show the audience how we got there. To call Greaves a genius is not accurate. Brave definitely, but genius no. If he had approached this project with a solid vision, it might have approached genius.
This movie shows a very interesting view into the psyche, manners, and mannerisms of people in 1968. It was definitely a different time.
