'We' Review: A Fascinating Doc Exposing the Fractures in French Society Along One Railway Line 'We' Review: A Fascinating Doc Exposing the Fractures in French Society Along One Railway Line An outwardly modest observational doc that builds cleverly into an epic intellectual interrogation of France's multicultural project. Jessica Kiang, provided by FacebookTwitterEmail Director: Alice Diop With: Alice Diop, Ismael Soumaïla Sissoko, N’deye Sighane Diop, Pierre Bergounioux, Marcel Balnoas, Ethan Balnoas. (French dialogue) Running time: Running time: 115 MIN. Sarah Blum The public, the private and the deeply personal run on parallel tracks in French director Alice Diop’s documentary “We,” a series of vignettes of life along the RER B, a railway line running through the suburbs and exurbs of Paris out to the surrounding countryside. But as it gains momentum, this deceptively cunning documentary — which out of a lineup full of showier titles won the top prize in Berlin’s Encounters section — sees those parallel tracks converge and criss-cross unexpectedly, throwing off fascinating intellectual sparks of insight at the switching points.
