joolsd’s review published on Letterboxd:
A misleadingly megalomaniacal title for a very personal film. If there's a megalomania here, it's that of a child seeing the future and all its possibilities laid out before them. Yaël André uses a host of what seem to be family film archives as the backdrop for the story of a friend's madness and suicide. Sometimes the footage is directly illustrative, presented as if it is really them and their experiences, and sometimes used more abstractly in relation to the voiceover.
These passages vary in effectiveness, but the conceit of a kind of "mathematical mourning" that runs throughout is strong, and lends the film that peculiar melancholy you only find in scifi (borrowing from La Jetée, I guess). Definitely not a film that everyone will connect with, but those who do, you know who you are.
