Les Valseuses may have seemed avant-garde when it was released but it now seems to me to be offensive and rather pointless. There is nothing clever about bullying yobs on the prowl being totally selfish and treating other people, particularly women, badly.
Much better in every respect is Blier's later film Tenue de Soirée, again with Gérard Depardieu as a larger-than-life figure and again with Miou Miou. It is even franker in sexual content but much better written, wittier and strangely lyrical -- a bitter-sweet look, cruel yet tender, at human sexual desire, gay and straight. It's a much more mature work with an excellent supporting cast and I'm surprised it's not at the moment available in a region 2 subtitled version.
