Another title for this movie is 'Ceci n'est pas un film'. It's about love. There were subtitles above subtitles, so I had to pause it a couple of times. I think the images are meant to be a bit of visual poetry. They're triggers for certain types of emotions and you hear or read the text.
"What cannot be forgotten reappears in dreams", what a great quote! I know someone else used it in their review, I am going to do so again, please forgive me :-) Like other great Situationist films (Venom and Eternity!), I need to watch this 3 times just to read the text. The 4th viewing I will be able to really look at the images. Radical politics from the perspective of a cinemaphile!
