Tabu, the third feature by the talented Portuguese director and critic Miguel Gomes, at first appears to be all about two things: one, Portugal’s colonial past and postcolonial present, and two, the current austerity policies that are choking the country’s poor and working classes. But these politically charged themes turn out to be only a small part of the picture. The film’s main theme is about what human life really comes down to: love and happiness, love and pain, love and loss, and love and regret. If you find Tabu’s story uninteresting, your heart is made of stone. If you find its cinematography unremarkable, your eyes are made of wood. (Northwest Film Forum, 1515 12th Ave,, 7 and 9:15 pm, $10)
