Took my little tribe, kicking and screaming as usual when a French-spoken film is concerned, to "Les Poupées Russes". This film from Cédric Kaplisch is the "some years later" sequel to "L'Auberge Espagnole". Young Europeans and their Europe-wide relationships, that's the main thing. Some of us from more open-to-the-outside-world peripheral countries without dubbing in home television, inter-rail fans or summer beach girls-chasers have been there for quite some time. Now, after Erasmus exchanges, it is becoming the norm. We all have friends now that are not from our safe mono-lingual neighbourhood.
That cosmopolitanism, and its corollary, I mean, speaking many languages and not just your own, has been typical of the cultivated elites in Europe for centuries (particularly among the aristocratic class). What is relatively new, and indeed revolutionary, is that it's becoming a mass phenomenon.
Apart from that, "Russian Dolls" worked for me in two other aspects. One, the attitude of the Russian bride towards his totally drunk groom on the wedding party. She laughed and was tender and understanding. (Most non-Russian young newly-weds would go straight to tragedy mode and make things worst. Learn with the Russian Dolls, babies!).
Two, the philosophical concept of the film, as stated in the end by the main actor. A guy has many experiences, girl after girl, just like the successive "matrioshkas" one plays with, until you get to the final one. But, I would enigmatically ask the Honourable Reader to consider, what if the last Matrioshka is a Russian doll indeed?
