Fear Factor (8pm, NBC) - In a desperate attempt to recapture the tiniest bit of an era when they weren't perpetually in last place, NBC has resurrected their roach-eating reality show of dares. They've even brought back the original "Fear Factor" host, an inked-up Joe Rogan (right). Two new back-to-back episodes tonight. In the first, contestants must eat five scorpions, get strapped to the front of a cement mixer, and hop onto the back of a truck that is heading toward an explosive collision with a barrier.
I Want a Dog for Christmas, Charlie Brown (8pm, ABC) - Linus and Lucy's little brother ReRun spends the holidays hanging with Snoopy and his brother Spike. Not the best Peanuts cartoon, but still about a hundred times better than "Fear Factor."
Stephen King's Bag of Bones (9pm, A&E) - The conclusion of the two-part movie about a novelist (Pierce Brosnan) grieving the loss of his wife. The man spends time at a lakeside home where he befriends a widow and her daughter and is visited by the ghost of a blues singer. If you missed the first part last night, it repeats tonight at 7.
The Closer (9pm, TNT) - A man is murdered while under FBI surveillance, stirring up friction between the federal agents and the LAPD. Meanwhile, Brenda's parents arrive for the holidays with some surprising news.
Enlightened (9:30pm, HBO) - In the first season finale, Amy finally persuades Levi to seek treatment after a breakdown in the middle of the night. At work, Amy defies Dougie to make a presentation to Damon's group, no matter the outcome, and she finds an unlikely ally to change the environment at Abaddonn.
Rock Center with Brian Williams (10pm, NBC) - Correspondent Chelsea Clinton makes her TV correspondent debut tonight with a profile of the founder of a mentoring program for school children in Pine Bluff, Arkansas.
