The French director Cédric Klapisch is a glib wizard at weaving folks together, but there are too many secondhand characters roving through Paris, his latest ensemble piece.There's the young man (Romain Duris) who may have a fatal heart condition; his caretaker sister (Juliette Binoche); the jaded professor (Fabrice Luchini) who stalks a student (and embarrasses us with his ''rock dancing''); his polar-opposite brother (François Cluzet) — all diagrammed to evoke the old/young, archaic/modern paradox of life in Paris.
But there's no denying that it all plays.
