This was a good week for welcoming back familiar and much-missed talent to some very good shows. Let's start with one of cable's underdogs, TNT's gritty and gripping police drama Southland, which introduced Carl Lumbly (who'll always be Dixon from Alias to me) as the squad's militaristic new captain, Brucker. "Our job just got harder," grumbles one of the grunts. Bad for him, good for Southland. Pledging to command a pro-active patrol, with Mickey D applications at the ready for those who screw up, Brucker's mantra is: "We protect! We serve! And we kick a— till we smell s---!" Yeah, he's that kind of boss.
