Easily one of the strongest films on display at this year’s icy Berlin Film Festival and a firm contender for best feature of 2012 so far, Portuguese director Miguel Gomes (perhaps best-known on these shores for his previous film, 2008’s This Dear Month of August) returns triumphantly with Tabu (2012). A beguiling black and white drama that spans both decades and continents, this is mesmeric, conscientious filmmaking at its most ambitious and expansive.
