Leave it to J.J. Abrams to distill post-9/11 paranoia and fear and turn it into great television.

In "Person of Interest" (9 tonight, CBS), Jim Caviezel is a former CIA agent with a mysterious past who ends up working for Michael Emerson, a scientist who has developed a way to see when crimes are going to be committed. The system lets them know who will be the victim, but not when or why. That's for Caviezel's character to unravel. Taraji P. Henson plays a cop trying to figure out what the heck is going on.

Caviezel channels Clint Eastwood as Dirty Harry; he kick butts effectively and speaks with economy. Emerson is quirky and fastidious. This is the best odd couple of the season.

Abrams has hurt me before after developing a show with a great start ("Alias"!!). Please, please let this show stay as excellent as the pilot.

As I watched "Unforgettable" (10 tonight, CBS), I imagined someone seeing the episode of "60 Minutes" with the report on the people with hyperthymesia -- that condition that allows folks to recall every moment -- and saying 'That could be a show!'

And so it is; a cop show, of course. Poppy Montgomery plays a detective who has left the force because remembering everything can apparently be tortuous. She's pulled back into police work when a crime is committed near her building and her ex-boyfriend (Dylan Walsh) happens to lead the local homicide unit. 

"Unforgettable" doesn't live up to it's name; instead it's perfectly pleasant.

"2 Broke Girls" (8:30 tonight, CBS) isn't as hilarious as "Bridesmaids" but if you saw and you liked that movie, you should like this crass, edgy sitcom. It's like "Two and a Half Men" with chicks.

Max (Kat Dennings) is a tough working-class waitress who ends up rooming and starting a business with Caroline (Beth Behrs), a bankrupt heiress, spawned by a Bernie Madoff type. Caroline annoys, then wins over Max; because she has been rich and is educated, Caroline's more hopeful, offering Max some inspiration. I liked Dennings more than Behrs, but they both worked in their roles.

Listen for the Duke sex joke delivered by co-star Garrett Morris.

The big news: Ted Danson is heading to "CSI."

The big question: Is this something that could finally get me to try to watch at least one full episode of "CSI?"

Danson is best known for his comic portayal of Sam Malone on the long-running NBC sitcom "Cheers," and then spent six years heading the CBS sitcom "Becker." But Danson can definitely do drama, as fans of "Damages" can attest (Danson was nominated for an Emmy for playing the rotten CEO, Arthur Furbisher). Danson also currently stars on the HBO series "Bored to Death," and he's absolutely hilarious there, and makes occasional appearances on Larry David's "Curb Your Enthusiasm."

As far as cliffhanger finales go, the "How I Met Your Mother" capper to season six offered slightly more suspense than your average stumble off a stepladder.

Ted resists reuniting with Zoey? Yawn. Lily is not throwing up because of food poisoning but because she's pregnant? Anyone who's watched more than two hours of American sitcoms could have predicted that "twist."

But a flash forward revealing that Barney is the groom in the wedding hinted at in the season's first episode? That works.

The smart money has Robin as the bride, even after Monday night's episode ended with Barney and Robin considering and then discounting the possibility of a rekindling of their romance. The last second appearance of Robin's British friend who Barney briefly dated seems like an obvious red herring.

But we can all agree with Barney and Robin's description of Ted and Zoey's romance, likely couched in a meta maneuver by the show's writers as an acknowledgment of the relationship as a wrong turn this season, as the worst thing ever.

Or maybe that will be Marshall and Lily's baby, for those of you who vowed to stop watching whenever that blessed event occurred.

CBS canceled some $#*! today, including the Twitter-inspired William Shatner sitcom "$#*! My Dad Says."

They also canceled the "How I Met Your Mother" copycat sitcom "Mad Love," which starred Sarah Chalke and Jason Biggs, and the pretty good legal dramedy "The Defenders," which starred Jim Belushi and Jerry O'Connell.

No word yet on CBS bubble shows "CSI: NY" and "Criminal Minds: Suspect Behavior." We'll update you when something happens with those.

"How I Met Your Mother" tipped its viewers off weeks ago that Ted and Zoey's relationship was doomed. So Monday's breakup was hardly a surprise.

Still, give credit to Ted for crafting the perfect breakup line.

My mother, an educator, believes teachers are born, not made.

"Beyond the Blackboard" (CBS, 9 tonight) is the sweet, inspiring, and yes, a little sappy story of a young woman born to be a teacher and the challenges she faces on her first job that turn her into a better one.

Emily VanCamp plays Stacey Bess, a young woman who always wanted to teach; her calling was interrupted when she got pregnant in high school and married. We meet her later as the young mother of two with a loving husband. She's finished her education and is looking for her first teaching job. The school board's personnel director (Timothy Busfield) has just the spot for her and she can start right away; it's teaching homeless children at a special school created because the itinerant children can't register at typical schools. (A law has since passed changing that.)

Well, at least one family mystery has been solved.

Maybe casting John Lithgow as Barney's father Jerry, the suburban driving instructor starting over with a new family, is just another example of this show's proclivity for guest star cameos.

Or maybe, if we're lucky, this HIMYM story arc is an origin story for Lithgow's unforgettable Trinity killer from the "Dexter" series' fourth season.

Watching NCAA tournament games will be a little different this year.

In a move to keep March Madness out of the hands of ESPN, CBS last year partnered with Turner Broadcasting System on a $10.8 billion deal which keeps the tournament in their control through 2024.

That deal also means that this year, many of the tournament games will be played on Turner cable channels instead of on CBS. That's both good and bad for basketball fans.
