Agnes Varda and Jacques Demy were two well-known French directors who both pushed boundaries and consistently put out personal, stylistic films. They also happened to be married for about 30 years.
In 1990, Demy was tragically dying from HIV/AIDS. This film appears to have been made at least in part right before his death, as it features some documentary footage/interviews with him, but the bulk of the film isn't a documentary, and presents a somewhat fictionalised depiction of Demy's life as a boy, teenager, and then a young man. It aims to explore the important periods of his life that inspired his films, and serves as a love letter from a filmmaker wife to her filmmaker husband.
In telling a coming of age story about a young boy interested with making movies, this reminded me quite a bit of both Cinema Paradiso and the recent Steven Spielberg film The Fabelmans. I don't think it's quite as good as the latter, and it's definitely nowhere near as good as the former... but in the case of Cinema Paradiso, that honestly might just be the Ennio Morricone difference - his music sort of makes that film, and adds to the emotional impact of it all.
However, when considering the backstory behind Jacquot de Nantes, it becomes a good deal more touching and bittersweet, and at least some of that backstory is made clear in the text itself. It doesn't give you everything like a full-on documentary might, but you get enough context for things to be quite moving by the end. It's certainly a personal film and I can appreciate some of its emotional weight, but I think structurally and narratively, it can be kind of repetitive and even a little tedious in places.
