Just watched the film again to refresh myself with it, in many ways it recalls Rohmers films and also reminded me of Broken Wings due to the grief factor, arsaib4's review is spot on which doesn't leave me with much to say. 

I liked the way that Olga was kept as "That Obscure Object of Desire" the untouchable perfection and lets face it, often in these cases it's best to leave these as fantasies as the reality can never live up to expectations.

Le Chignon d'Olga is a gentle film with moments that most of us will be able to connect with, it is a more than pleasant way to while away 90+ minutes and comes thoroughly recommended.

Cheers Trev.
