CSI: Miami

CSI: Miami
10/9c CBS
The crime-fighting series, now in its ninth season, celebrates its 200th episode with an hour titled, appropriately enough, "Happy Birthday." Horatio, who last week showed his contempt for anyone who harms a woman by tossing an abusive suspect through a window, is again incensed when a pregnant woman is severely beaten and left for dead after her car is smashed into by another vehicle. Of course, it was no accident. The woman was targeted. But why? Don't worry, H is on the case. — Tim Holland

Marge gets yuletide decorating help from Martha Claus (voiced by Martha Stewart) and the family plans a Hawaiian holiday getaway, but a surprise visit from Katy Perry, who plays herself in a live-action sequence with puppets of the Simpsons, delays their departure. — Fred Mitchell

Boardwalk Empire
9/8c HBO
Last week, the thrilling first season's penultimate episode was full of surprises, including the revelation of Jimmy's paternity, the forced resignation of Eli and Sebso's murder by Van Alden. It also set the bar pretty high for tonight's finale, but series creator Terence Winter probably has a few more tricks up his sleeve, namely how the Nucky-Rothstein feud will shake out, whether Margaret will come back to her benefactor and how Jimmy will deal with the woman who was ready to desert him. — Joe Friedrich

The Steelers visit the Ravens in Baltimore, so if you're hankering for an offensive shootout, you might want to rent a western. These defensive powers have ranked first and second, respectively, in the NFL over the last four years in total yards allowed, and are among the league's upper echelon again this season. The Ravens already have a thrilling win over their rivals this year in Pittsburgh, getting a TD reception from T.J. Houshmandzadeh with 32 seconds left to earn a 17-14 victory. That was the fifth consecutive regular-season meeting between these teams decided by four points or fewer. — Dave Roeder

The Hasselhoffs
10/9c A&E
One memorable time the public had a glimpse into the personal life of David Hasselhoff, it wasn't pretty. The actor-singer weathered a 2007 drunken cheeseburger-eating incident — he subsequently noted he'd been dealing with alcoholism — and now he's giving fans full access to his personal life in a reality series that follows him, as well as his daughters, Taylor and Hayley. In the opener, he visits Taylor in Arizona to persuade her to stay in school, and Hayley gets a role on a TV series. — Bill Ecklund

The Walking Dead
10/9c AMC
On the pulse-pounding chiller of a Season 1 ender, the survivors reach the Center for Disease Control complex in Atlanta. There they are welcomed by the doctor (Noah Emmerich) in charge of the facility, and he provides them with showers, beds, food and booze, but not a lot of hope. What he can't facilitate is a foolproof path to safety. He does, however, offer them some insight into what happens to an infected person, and it might be "microbial, viral, parasitic, fungal...or the wrath of God." It is one helluva finale. — Ray Stackhouse
