As far as season premieres go, “Simple Pleasures” does an excellent job of making you feel like you haven’t missed one second of living with the Gallaghers as you experience all the ups and downs of their lives. It’s almost like the show hasn’t been on hiatus since last April. The episode is filled with happiness, sadness, great acting as usual, sharp and witty dialogue, and makes me wish I could watch all of this season’s episodes at once.
