Vampire Diaries
8/7c CW
Kevin Williamson, the creator of Dawson's Creek and the Scream fright flicks, combines two of his favorite things — teens and horror — in his promising adaptation of the pre-Twilight young-adult book series that nevertheless owes its TV existence to Twilight's mega-success. In tonight's predictable but polished opener, Stefan (Paul Wesley), a centuries-old vampire who doesn't look a day over 19 and refuses to drink human blood, returns to his Virginia hometown to pursue a high-school student (Nina Dobrev) who reminds him of a long-lost love. Of course, Stefan's evil brother (Ian Somerhalder) shows up to complicate things. — Tim Holland

NFL Opening Kickoff 2009
8/7c NBC
This year's sixth annual salute to the Super Bowl-winning team features three-time Grammy winners Tim McGraw and the Black Eyed Peas performing in a free concert in Pittsburgh, hosted by Saturday Night Live's Seth Meyers. Don't expect to see much of any of them — the show's only a half hour. Pro-football fans will want to stay tuned for the main event at 8:30 pm/ET as real honest-to-goodness NFL games get underway, with the Pittsburgh Steelers hosting the Tennessee Titans. — Dave Roeder

Big Brother 11
8/7c CBS
Who will be the two finalists who will compete for jury votes on Tuesday and the $500,000 grand prize? The last Head of Household competition will go a long way in determining which of the three remaining houseguests (Jordan, Kevin, Natalie) will be evicted later tonight. It's certainly the most important showdown of the season. — Tim Holland

9/8c CW
All hell breaks loose — literally — as the fifth season of the supernatural thriller begins. Fans will recall from last season's finale that Lilith's death broke the 66th and last remaining seal that kept Lucifer (Mark Pellegrino) confined to hell. Now he is free to roam the Earth and cause destruction at will. Looks like Sam and Dean have their work cut out for them this year. — Tim Holland

Project Runway
10/9c Lifetime
Our threaders made waves in the previous episode when they took a fashion field trip to the shores of California and designed fun surf wear, complete with an avant-garde companion piece. Cool Ra'Mon rode the wave to a win, but life was a beach for wipeout victim Mitchell. With the Season 6 needling already spiking (Epperson vs. Qristyl), we move onward. Thirteen is the lucky number when the group is slated to create clothes for 13 folks of the fairer sex tonight. — Dean Maurer

Ace of Cakes

When NFL superstar Tom Brady needs a cake, Duff and Co. get busy. They create a confection for the Best Buddies International gala, which will be hosted by the Patriots quarterback. Meanwhile, Ben works on an elaborate robot cake inspired by Doctor Who. Later, the Charm City Cakes crew takes to the paintball field to settle some bakery grievances, and Duff and Mary Alice make their long-awaited stage debut. — Karen Andzejewicz
