Easy to watch, hard to digest. "Styx" is a good and soft-voiced political film, but maybe too long for its simple message about individual responsibility. Or maybe there's just too much message and too little drama in this film. It has a great analogy of Europe as naval crisis between an immigrant boat, a private boat and coastal guard. The grand political scenario of immigrant politics is dramatized in scale of two boats. If you get a mayday message on sea then it is the kind of situation where you must help anyone in need. But the lonely sailor (Susanne Wolff) of the private boat must decide how long will she use her own small boat and believe in her own devotion (she's a doctor) to help +300 immigrants in a sinking boat miles away from African west coast.
