Confession: I didn't even watch "The Bachelor" last night (too many DVR conflicts now that "The Voice" is back!) but I did monitor the situation in Panama so that I could report to other slackers that Blakeley Shea, the Charlotte/Rutherfordton contestant, was eliminated in last night's show.

Blakeley (left) ended up as one-half of the dreaded two-on-one date last night, which means two women leave for the date and only one woman returns. Reports indicate the date included Latin dancing and a weird "scrapbook of feelings" (made by a weepy Blakeley). Let's face it. Even a "VIP Waitress" from holy Charlotte cannot pull off a stalkery move like that, and Blakeley was dismissed. Blakeley was livid and stormed out in tears without speaking to bachelor Ben Flajnik.

In other local developments, Emily O'Brien, the Duke grad and UNC-Ch PhD student . . .

ABC has gone pretty darn creepy with their newest drama offering.

"The River," which has a two-hour debut tonight at 9, follows a group of fools (I believe that's the technical term) as they search the Amazon for a celebrity naturalist who, along with his entire crew, has been missing in the jungle for six months.

The search for Emmet Cole (Bruce Greenwood), the popular star of the "Undiscovered Country" series, quickly turns into a creepy, supernatural nightmare for everyone involved.

Can "Smash" save NBC? Well, it certainly can't hurt. And the Peacock needs this one. Bad.

Here's the nutshell version of tonight's big series debut (10 p.m.), in case you've missed the nine million promotional spots NBC has been pushing for weeks (but considering how few people actually watch NBC, maybe the pilot isn't as overexposed as many believe?):

"Smash" is a musical drama about a group of Broadway producers attempting to stage an original show about the life of Marilyn Monroe. It has a great cast (Debra Messing, Angelica Huston, Katharine McPhee), great original music, and lavish choreography.

Even for the most casual theater fans, "Smash" is an intoxicating insider's look at putting on a Broadway show, from the first spark of an idea through financing and casting, all the way to opening night.

Duke senior Greer Mackebee, 22, will compete for the $100,000 grand prize in the “Jeopardy!” College Championship tonight. Mackebee, pictured here with "Jeopardy!" host Alex Trebek, is a native of Knoxville, Tennessee. "Jeopardy!" airs locally at 7 p.m. on WTVD.

Smash (10pm, NBC) - This much-hyped debut of NBC's (much better!) answer to "Glee" follows a group of professional adult people staging a Broadway show. In tonight's debut, a writing duo come up with the idea to base a musical on Marilyn Monroe, and an experienced chorus girl competes against a promising newcomer. It has a great cast, which includes Debra Messing, Angelica Huston and Katharine McPhee. Here's my full review.

Lost Girl (10pm, Syfy) - Bo protects a human woman after a fury tries to hire Bo to kill her husband's mistress.
