I have this problem with Demy: his movies are enjoyable, glittering, cheerful, but most of them, eventually, plainly empty. And that fact bothers me. The only one that was not was 'The Umbrellas of Cherbourg'. Deneuve obviously is not a dancer, haha, but she's still magnificent. Easy to watch and relaxing movie for a sad afternoon will make everyone feel better!
The dance numbers are spiffy. The casualness with which everyone in the movie accepts everything from french fries to a dismembered body is odd and left me disengaged. If the people in the movie don't care, neither do I.
Learning Deneuve and Dorléac were real life sisters is quite interesting. The film is incredible. The seemingly alternate universe where even murder can be bright is interesting, and brings (a bit) of realism. But I love it. It's a great accomplished vision and production design heaven. I want to rewatch it!
