SEASON PREMIERE: The Good Wife ended last season with Alicia (Julianna Margulies) answering her door, and greeting Cary (Matt Czuchry) with the news that she would join him in his effort to defect from Lockhart/Gardner and start a new law firm. “I’m in,” she said – and so are we, for a reboot that promises to shake things up on a seismic scale. What kind of betrayal does that feel like, to Diane Lockhart (Christine Baranski) and Will Gardner (Josh Charles)? For very different reasons, they feel like very different types of betrayal.
