'Boardwalk Empire' returns

Get ready for some more action on the Boardwalk. The fourth-season of "Boardwalk Empire" premieres 9 p.m. Sunday on HBO, and the Atlantic City-based drama is as good as ever, despite a kick-off episode that is dark and sometimes muddled.

Some fans may find themselves wondering where this is going and whether they want to go there with it. You will (believe me, you will), but just gird yourself for something new, and in surprising ways, something better. "Empire" is richer, deeper, and - if possible - even more beautiful.
