SEASON PREMIERE: For its ninth and final season (which will unfurl in two separated chunks, as The Sopranos did), Shameless returns to the incendiary topics that it played with last season, including the “gay Jesus” movement. And this year, Frank Gallagher (William H. Macy) dives deeper into Chicago politics, a swamp where he should feel extremely comfortable. There are so many excellent actors in this series – and so many great Gallaghers, including Emmy Rossum and Cameron Monaghan – that it’s reasonable to expect Shameless will go out with a bang.
