9 pm/ET Showtime
Season 3 comes to a well-executed conclusion. The episode title, "Do You Take Dexter Morgan," is ambiguous and can relate to Dexter's impending nuptials to Rita, or to the possibility that he can be taken out by a vengeful someone with a grudge against him. Someone like Ramon, Miguel's temperamental and unpredictable brother. (As if there isn't already enough to be concerned with on one's wedding day.) In other Morgan-related news, Debra learns she's getting her detective's shield, but some lurking bad news could tarnish her promotion. — Ray Stackhouse

Survivor: Gabon --- Earth's Last Eden
8 pm/ET CBS
"Good vs. evil." That was the theme hyped for this season and, although it took awhile for it to develop, it did finally emerge. And now that the finale is here, there are more so-called good guys and gals left than evil ones, but who will ultimately claim the $1 million top prize? Whoever takes the cash will first have to endure more challenges, tribal councils and face a jury of their peers they had a hand in voting out. Good luck to all. They'll need it. — Tim Holland

Snow 2 Brain Freeze
8 pm/ET ABC Family
Tom Cavanagh returns as Nick Snowden (aka Santa Claus) in this sequel to the 2004 comedy Snow. With just a few days to go until Christmas, Nick can't remember that he is indeed Santa, thanks to a bump on the head that gives him amnesia. His wife, Sandy (Ashley Williams), does her best to try and help him remember, even enlisting help from her ex-boyfriend, Buck. And Buck is more than happy to "pretend" to help Sandy as Christmas fast approaches. — Jennifer Sankowski

Sunday Night Football
8:15 pm/ET NBC
For the Giants, tonight's game in Dallas offers the opportunity to show last week's loss to the Eagles was no big deal and to reestablish themselves as the 800-pound gorilla of the NFC. For the Cowboys, it's more: Last weekend's defeat by Pittsburgh leaves them in wild-card contention, but not by much. A loss tonight could make for a very long January in Dallas. — Dave Roeder

House of Saddam
9 pm/ET HBO
As the old saying goes, there's no place like home, and that's fortunate when the abode in question belongs to a delusional, psychotic Saddam Hussein. The second half of this HBO-BBC miniseries picks up with UN sanctions in the mid-1990s, but the drama heats up when an Iraqi general pays the ultimate price for crossing his father-in-law president, then it comes to a boil in the aftermath of the 2003 invasion by U.S. forces, which sealed the well-documented fate of Hussein and his sons, Uday and Qusay. — Joe Friedrich
