It’s kind of been a minute since we heard from Swedish writer/director Lukas Moodysson, at least in the world of film. Known for his often tender, heartfelt, and yet uncompromising works generally centered around children or coming of age tales, Moodysson made his name with films like “Show Me Love” and “Lilya 4-ever.” His last film, however, was 2013’s exuberant teen/punk coming of age film “We Are the Best!” and it’s been mostly silence since—even for his career as a novelist (his last book is 2012). Whatever the reason for the break, the filmmaker finally returns and now in series form with “Gösta,” a twelve-episode show for HBO Europe.
