“Alcohol is the death of dignity.” This latest oddity from DIY enthusiast Michel Gondry offers a quirky Gallic antidote to a dreary diet of American teen movies. A coming-of-age yarn spun by an overage kid, writer/director Gondry’s sweet-natured adventure comes on like a benevolent version of The Selfish Giant crossed with a particularly bonkers episode of Here Come the Double Deckers!. Two misfit kids go scrapping for junk and build a house/car hybrid for a cross-country trek. It’s erratic stuff, often amusing, occasionally ill judged, but packed with off-kilter, ramshackle charm.
